Adjustable vehicle suspension system
A damping control system for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame includes at least one adjustable shock absorber having an adjustable damping profile and a driver actuatable input. The driver actuatable input may be positioned to be actuatable by the driver in the absence of requiring a removal of either of the hands of the driver from a steering device of the vehicle.
Adjustable suspensions and vehicle operation for off-road recreational vehicles
Suspension systems for recreational vehicles are disclosed. The suspension systems may include at least one adjustable member coupling a sway bar to respective suspensions. The suspension systems may include a torque actuator associated with a sway bar.
Methods and apparatus to use front load estimates for body control
Methods, apparatus, systems, and articles of manufacture are disclosed to use front load estimates for body control are disclosed herein. An example apparatus disclosed herein includes memory including stored instructions, and a processor to execute the instructions to filter sensor data to generate a first load value, the first load value associated with a first load on a front axle of a vehicle, generate, based on the first load value and a velocity of the vehicle, a first body control adjustment value, modify a body control output value with the first body control adjustment value, and apply the modified body control output value to a suspension system of the vehicle.
Rear suspension assembly and method of controlling a rear suspension assembly
A snowmobile including a chassis including a tunnel; a motor; at least one ski; an endless drive track; a rear suspension assembly including: a front suspension arm; a rear suspension arm; a pair of slide rails; a first rear shock absorber connected between the front suspension arm and the slide rails; and a second rear shock absorber connected between the rear suspension arm and the front suspension arm or the slide rails; at least one sensor for sensing an angular position of the front suspension arm or the rear suspension arm relative to one of the tunnel and a component of the rear suspension assembly near at least one of the front suspension arm and the rear suspension arm; and a controller communicatively connected to the sensor to receive electronic signals therefrom representative of the angular position.
Supporting structure of wheel speed sensor
A front wheel caliper bracket for supporting an axle is provided in a lower end portion of a front fork. A wheel speed sensor is mounted on the bracket. The wheel speed sensor includes a fixing section and a sensor section, and is mounted on a sensor mounting section of the bracket by a bolt. The sensor mounting section is integrally formed with a rotation regulating portion in a projecting fashion. When fastened by the bolt, a lateral part of the rotating wheel speed sensor comes into contact with the rotation regulating portion to regulate the rotation of the wheel speed sensor, so that the stress from the rotation regulating portion is not exerted directly on the sensor section.
DAMPING FORCE CONTROL DEVICE
A damping force control device 10 comprises vary damping shock absorbers, a detector, and a controller. Each of the shock absorbers sets damping coefficient from a minimum value to a maximum value in order to adjust damping force. The detector detects vertical vibration state quantity relating to vibration of the sprung mass. The controller performs an ordinary control for setting the damping coefficient based on the vertical vibration state quantity and according to a predetermined control law suitable for an assumption that all of the wheels touch ground. The controller performs, when at least one of the wheels is an ungrounded wheel which does not touch the ground and each of the other wheels is a grounded wheel which touches the ground, a specific control for setting the damping coefficient of the shock absorber corresponding to the grounded wheel to a first specific value greater than the minimum value.
ELECTRIC SUSPENSION APPARATUS AND METHOD FOR CONTROLLING ELECTRIC SUSPENSION
The electric suspension apparatus is mountable in a vehicle and includes: an electric actuator configured to perform a stroke operation in response to behavior by the vehicle; a motor configured to drive the electric actuator; a rotation angle sensor configured to detect an angle of rotation of the motor; and a controller configured to control the electric actuator, wherein the controller calculates a stroke amount for the electric actuator based on an amount of change in the rotation angle detected by the rotation angle sensor, and controls the electric actuator based on the calculated stroke amount.
Look ahead vehicle suspension system
A wheel based vehicle configured to travel along a roadway environment, the wheel based vehicle comprising: a first independent suspension element, a second independent suspension element, at least one electromagnetic sensing device, and processing circuitry. The first independent suspension element is configured to service a first wheel with a first suspension performance. The second independent suspension element configured to service a second wheel with a second suspension performance. The at least one electromagnetic sensing device is disposed and configured to capture image data of the roadway environment. The processing circuitry is configured to: identify, based on the captured image data and vehicle motion data, first future predictions of first drive situations to be accommodated, and second future predictions of second drive situations to be avoided; and accommodate the first future drive situations by selection of a third suspension performance for the first independent suspension element.
Method for controlling a vertical vibration damping of at least one wheel of a vehicle and vehicle vertical vibration damping of at least one wheel
A method for controlling a vertical vibration damping of a wheel of a vehicle, in which the wheel has a suspension including a vibration damper with a control element including an actuating element for adapting a damping characteristic of the vibration damper includes a series of steps. The vehicle includes a first sensor for detecting roadway anomalies, a second sensor for detecting a vertical displacement of the wheel, and a control unit connected to the first and second sensors and the control element. The method steps include detecting roadway anomalies with the first sensor, detecting the vertical displacement with the second sensor and switching the vibration damper with the control element at a first point in time from a first state with a first damping characteristic into a second state with a second damping characteristic when a first sensor signal generated by the first sensor indicates a roadway anomaly with a minimum height.
