DETAILED DESCRIPTION

[0030] Vehicle owners may decide to replace the OEM (original equipment manufacturer) wheels on their vehicle with aftermarket wheels. Each wheel includes a tire and rim package. Wheel diameter refers to an effective rolling diameter of the wheel. The aftermarket wheels may have a larger diameter or smaller diameter than the OEM wheels. Lowering an adjustable ride height system of the vehicle may result in contact between a body of the vehicle and aftermarket wheels that have a larger diameter than the OEM wheels. And the larger diameter aftermarket wheels may result in the vehicle being raised undesirably high by the adjustable ride height system. If the aftermarket wheels have a diameter that is smaller than the OEM wheels, then lowering the adjustable ride height system of the vehicle may result in contact between the body and the ground. Aftermarket wheels that are larger than OEM wheels may also result in contact between the wheels and the body when the wheels are turned fully to the left or to the right. The present disclosure provides for a system configured to modify limits of at least one of vehicle ride height adjustability and wheel pivot distance based on a detected wheel diameter of aftermarket wheels. Although the examples described herein are directed to vehicle applications, the present disclosure applies to non-vehicular applications as well.

[0031] FIG. 1 illustrates an exemplary system 10 in accordance with the present disclosure. The system 10 includes a control module 20 configured to receive inputs from a global positioning system (GPS) receiver 30 and a wheel speed sensor 32. Based on the inputs, the control module 20 is configured to modify limits of an adjustable ride height system 40 and/or control a steering system 42 to modify wheel pivot distance limits, as described in detail herein. The adjustable ride height system 40 is any active suspension system or other system configured to raise and lower a vehicle body relative to the wheels of the vehicle. The steering system 42 may be any suitable steering system for the wheels of the vehicle configured to set varying limits of pivot to the left and right, as described further herein. The steering system 42 may be a dynamic rack travel steering system, for example.

[0032] FIG. 2A illustrates an exemplary vehicle 110 including the system 10. The system 10 may be configured for installation in any suitable non-vehicular application as well. With respect to the vehicle 110, it includes a body 120 with a fender 130. A wheel well 140 is at least partially defined by the body 120. The vehicle 110 may include any suitable number of wheels, such as four wheels. Only one of the four wheels is illustrated. The following description of the illustrated wheels applies to all of the wheels, which will typically be the same.

[0033] In the Example of FIG. 2A, mounted to the vehicle 110 is a standard wheel 150A, which is an OEM wheel with a standard wheel diameter. A standard clearance A is defined between an outer diameter of the standard wheel 150A and the fender 130 when the adjustable ride height system 40 is at a neutral position (such as halfway between a maximum lowered position and a maximum raised position).

[0034] FIG. 2B illustrates the vehicle 110 with the standard wheel 150A (the OEM wheel) replaced with an oversized wheel 150B. The oversized wheel 150B has a maximum diameter that is greater than a maximum diameter of the standard wheel 150A. As a result, a reduced clearance B is defined between an outer diameter of the oversized wheel 150B and the fender 130 when the adjustable ride height system 40 is at the neutral position.

[0035] FIG. 2C illustrates the vehicle 110 with the standard wheel 150A (the OEM wheel) replaced with an undersized wheel 150C. The undersized wheel 150C has a maximum diameter that is less than a maximum diameter of the standard wheel 150A. As a result, an increased clearance C is defined between an outer diameter of the undersized wheel 150C and the fender 130 when the adjustable ride height system 40 is at the neutral position.

[0036] FIG. 3 illustrates exemplary control logic 210 of the system 10 or any other suitable system configured to modify limits of at least one of vehicle ride height adjustability and wheel pivot distance based on a detected wheel diameter. The system 10, and particularly the control module 20, is configured to execute the control logic 210. From starting point 220, the control logic proceeds to block 230. At block 230, the control module 20 determines whether the vehicle 110, or any other suitable vehicle, is equipped with at least one of the adjustable ride height system 40 and the steering system 42. If at least one of the adjustable ride height system 40 and the steering system 42 is present, the control logic 210 proceeds to block 232, etc. Otherwise, the logic returns to repeat block 230.

[0037] At block 232, vehicle speed, such as speed of the vehicle 110, is determined based on GPS tracking. For example, the control module 20 is configured to regularly receive GPS signals from the GPS receiver 30 and identify the location of the vehicle based on the GPS signals. The control module 20 is configured to calculate the vehicle speed based on distance traveled over a period of time (vehicle speed = distance/time).

[0038] At block 234, the control module 20 is configured to identify wheel speed of one or more wheels 150 (such as the wheels 150A, 150B, 150C) in any suitable manner. For example, the control module 20 is configured to receive signals from a wheel speed sensor 32 representing wheel speed. Any suitable wheel speed sensor may be used, such as an anti-lock braking system (ABS) wheel speed sensor. The control module 20 is configured to measure the wheel speed of all of the wheels of the vehicle 110 and then average the speeds to arrive at an average wheel speed that is compared to vehicle speed measured using GPS. Thus, reference herein to wheel speed may be an average wheel speed of all the wheels of the vehicle. Alternatively, the wheel speed of less than all of the wheels may be used and compared against the vehicle speed measured using GPS.

[0039] At block 236, the control module 20 is configured to use the wheel speed sensor 32 to measure the wheel speed and use the GPS signals from the GPS receiver 30 to measure vehicle speed over any suitable distance interval, such as once every mile. The control module 20 is configured to compare the measured vehicle speed and the measured wheel speed taken at each distance interval. At each interval, there will typically always be a discrepancy (i.e., a difference) between the measured vehicle speed and the measured wheel speed, even when the vehicle 110 is equipped with the standard wheels 150A. The control module 20 is configured to store and track this discrepancy. For example, the control module 20 may be configured to store and track the discrepancy for the prior 100 miles. When measured once every mile, over 100 miles the control module 20 will store 100 discrepancy measurements between the vehicle speed and the wheel speed.

[0040] With the standard wheels 150A mounted to the vehicle, any discrepancy between the GPS vehicle speed and the wheel speed will be minimal (and possibly zero). For example, the discrepancy may be 1.2% or about 1.2% on average over 100 miles. As long as the discrepancy remains below a predetermined threshold, such as 1.5% or 2.0%, for example, the control module 20 is configured to determine that the vehicle 110 is equipped with the standard wheels 150A (which may be considered as the OEM wheels). As long as the vehicle 110 has the standard wheels 150A, the control module 20 is configured to keep standard OEM settings for the adjustable ride height system 40 and the steering system 42.

[0041] When the control module 20 determines that the discrepancy between the GPS vehicle speed and the wheel speed is equal to, or greater than, the predetermined threshold, the control module 20 is configured to determine that the standard wheels 150A have been replaced with non-standard wheels, and the control logic 210 proceeds from block 236 to block 238. At block 238, the control module 20 is configured to identify the diameter of the nonstandard wheels. For example, if the control module 20 determines that the wheel speed is 7% less than the vehicle speed, the control module 20 is configured to determine that oversized wheels 150B have been mounted to the vehicle 110. This is because the oversized wheels will rotate relatively slower than the standard wheel 150 over a given distance. The reduction in rotation of the oversized wheels 150B is proportional to the size difference between the standard wheels 150A and the oversized wheels 150B. Thus, a 7% reduction in wheel speed correlates to the oversized wheels 150B being 7% larger than the standard wheels 150A. If the wheel speed is 10% greater than the vehicle speed, then the oversized wheels 150B are 10% larger than the standard wheels 150A.

[0042] If the control module 20 determines that the wheel speed is 7% greater than the vehicle speed, the control module 20 is configured to determine that undersized wheels 150C have been mounted to the vehicle 110. This is because the undersized wheels will rotate relatively faster than the standard wheels 150 over a given distance. The increase in rotation of the undersized wheels 150C is proportional to the size difference between the standard wheels 150A and the undersized wheels 150C. Thus, a 7% increase in wheel speed correlates to the undersized wheels 150C being 7% smaller than the standard wheels 150A. If the wheel speed is 10% less than the vehicle speed, then the undersized wheels 150C are 10% smaller than the standard wheels 150A.

[0043] From block 238, the control logic 210 proceeds to block 240. At block 240, the control module 20 determines whether the diameter of the wheels exceeds safe tire flop and displacement travel within the wheel well 140. Tire flop is the space the wheel (hub and tire) can reasonably occupy within the wheel well 140. The wheel should be free from contact with the body 120 (such as the fender 130) as the adjustable ride height system 40 moves the body 120 up and down, and as the wheels rotate left and right. Displacement travel refers to the distance that the suspension can travel when exercised during driving without there being contact between the oversized wheel 150B and the body 120, and without there being contact between the body 120 and the ground when the vehicle is equipped with the undersized wheel 150C.

[0044] If at block 240 the control module 20 determines that the oversized wheel 150B is too large to allow for the same degree of suspension travel provided by the adjustable ride height system 40 when the standard wheels 150A are mounted to the vehicle 110, at block 250 the control module 20 is configured to raise a lower limit of the adjustable ride height system 40 so that the oversized wheel 150B will not contact the body 120 (such as the fender 130) when the suspension is exercised. At block 250 the control module 20 may also be configured to decrease an upper limit of the adjustable ride height system 40 so that with the oversized wheel 150B the vehicle 110 does not ride too high, which may affect aerodynamics.

[0045] At block 240 the control module 20 also determines whether the undersized wheel 150C is too small to allow the adjustable ride height system 40 to lower the body 120 to the lowest setting without the body 120 contacting the ground. If the control module 20 determines that ground contact will occur, at block 250 the control module 20 is configured to increase a lower limit of the adjustable ride height system 40 to a greater height as compared to the standard lower limit when the standard wheel 150A is used so that with the undersized wheel 150C the body 120 does not contact the ground.

[0046] At block 240 the control module 20 is further configured to determine whether the oversized wheel 150B will contact the body 120 (such as at the fender 130) when the oversized wheel 150B is pivoted to the left or the right by the steering system 42. FIG. 4 illustrates an example where due to the increased size of the oversized wheels 150B, turning the oversized wheels 150B to a maximum left position results in the oversized wheels 150B contacting the fender 130 when the steering system 42 is set to a standard pivot distance limit used for the standard wheel 150A. If the control module 20 determines that the oversized wheel will contact the body 120, at block 252 the control module 20 is configured to set a reduced pivot distance limit for the oversized wheels 150B that is less than a standard pivot distance limit used by the steering system 42 for the standard wheels 150A. The reduced pivot distance limit prevents the oversized wheels 150B from contacting the body 120 when pivoted to the left and to the right. From block 152, the control logic returns to 230.

[0047] From block 240, the control logic 210 may optionally proceed to block 260. At block 260, the control module 20 is configured to generate a notification to the driver or other operator of the vehicle 110 with a warning of the issues identified at block 240. For example, and with reference to FIG. 5, the control module 20 may generate a warning 310 notifying the driver/operator that the oversized wheels 150B may contact the fender 130 when turned to a maximum right or left position set for the standard wheels 150A. The warning 310 will give the driver/operator the opportunity to proceed operating the vehicle 110 with the steering limitations set for the standard wheel 150A. The warning may also be configured to allow the driver/operator to proceed operating the vehicle 110 using the upper and lower limits of the adjustable ride height system 40 set for the standard wheel 150A even though the oversized wheel 150B or the undersized wheel 150C may be on the vehicle 110. At block 262 the control module 20 is configured to give the driver/operator the option to approve an override of the new suspension limits set at block 250 and the new wheel pivot distance limits set at block 252. If the driver/operator approves the override, the control module 20 proceeds from block 262 to block 264 where the control module 20 allows the vehicle 110 to be operated without modification of the suspension height limits and the steering pivot limits set for the standard wheels 150A. The driver/operator may want to approve the override for a variety of different performance-related and non-performance related reasons, such as to customize the appearance of the vehicle 110. If at block 262 the driver/operator approves the override, the control module proceeds from block 262 to blocks 250 and 252 to set new limits.
