AIR SUSPENSION EVACUATION FOR IMPROVED BRAKING PERFORMANCE
The invention i.a. relates to a load transfer arrangement (10) for a vehicle (12) including a chassis (14) with at least one braked axle (16), the arrangement (10) comprising: a non-driven load axle (18), and an air suspension assembly (20) including at least one air cushion (22) arranged between the chassis (14) and the non-driven load axle (18) in order to transfer load from the braked axle(s) (16) to the non-driven load axle (18), wherein the non-driven load axle (18) is unbraked, and wherein the arrangement (10) further comprises: an evacuation controller (24) configured to provide a pressure release trigger in response to a current or predicted braking event of the vehicle (12), and at least one evacuation valve (26) configured to, in response to receiving the pressure release trigger, evacuate pressure from the at least one air cushion (22) in order to remove load from the non-driven load axle (18) and increase load on the braked axle(s) (16).
TORQUE CONVERTER CONTROL FOR A VARIABLE DISPLACEMENT ENGINE
Systems and methods for operating an engine and a torque converter are presented. In one example, slip of a torque converter is adjusted via at least partially closing or opening a torque converter clutch in response to vehicle vibration. The vehicle vibration may be based on road surface conditions and an actual total number of operating cylinders of the engine.
Parameters sets for vehicles based on sensor data
In some examples, a controller receives measurement data from a sensor on a vehicle, determines, based on the measurement data, a condition of usage of the vehicle, and selects a parameter set from among a plurality of parameter sets based on the determined condition of usage of the vehicle, the plurality of parameter sets corresponding to different conditions of usage of the vehicle, where each parameter set of the plurality of parameter sets includes one or more parameters that control adjustment of one or more respective adjustable elements of the vehicle. The controller causes application of the selected parameter set on the vehicle.
CONTROL OF A VEHICLE EMERGENCY BRAKING SYSTEM
A control system (100) for an emergency braking system (200) using at least one transmitter/receiver sensor (210) comprising: means for causing automatic transition, from a first state (310) in which the emergency braking system (200) is inactive to a second state (320) in which the emergency braking system (200) is active, in dependence upon satisfaction of a first group of different necessary conditions (412).
Torque converter control for a variable displacement engine
Systems and methods for operating an engine and a torque converter are presented. In one example, slip of a torque converter is adjusted via at least partially closing or opening a torque converter clutch in response to vehicle vibration. The vehicle vibration may be based on road surface conditions and an actual total number of operating cylinders of the engine.
DRIVE CONTROL APPARATUS FOR DRIVE SYSTEM OF VEHICLE
A drive control apparatus is applied to a drive system that is mounted to a vehicle, drives wheels of the vehicle by a motor, and brakes the wheels by a brake apparatus. The drive control apparatus determines a road-surface state of a travel road of the vehicle. The drive control apparatus suppresses slipping of the vehicle by correcting a drive torque by correcting at least either of a motor torque and a brake torque. When determined that the drive torque is to be corrected, the drive control apparatus adjusts a correction amount of the drive torque by adjusting the motor torque with higher priority than the brake torque in response to be determined that the road-surface state is rough.
METHODS AND APPARATUS TO ESTIMATE A SUSPENSION DISPLACEMENT
Methods, apparatus, systems and articles of manufacture are disclosed for estimating a suspension displacement. An example apparatus includes a suspension motion determiner module programmed to output a signal to a first suspension assembly of a vehicle based on a first deflection of the first suspension assembly, the first deflection calculated based on a calculation and a second deflection of a second suspension assembly of the vehicle, the calculation selected based on whether the vehicle is utilized in a first mode or a second mode.
TRANSPORTATION INFRASTRUCTURE COMMUNICATION AND CONTROL
Data is received from a vehicle in a stationary support structure. One or more physical attributes of an infrastructure element is determined based on the vehicle data.
Logical Configuration of Vehicle Control Systems Based on Driver Profiles
Apparatuses, systems, and methods are provided for the logical configuration of vehicle control systems based on driver profiles. A vehicle control computer may identify driving behavior of a driver of a vehicle through vehicle operation data provided by one or more of vehicle sensors, a telematics device, and a mobile device. Based on the driving behavior, the vehicle control computer may develop a first driving profile for the driver of the vehicle. The vehicle control computer transmit the first driving profile to a remote server storing driving profiles of a plurality of users. The vehicle control computer may download a second driving profile associated with a different driver from the remote server. The vehicle control computer may configure vehicle operations based off of the second driving profile associated with the different driver and may actuate vehicle operation based on the configuration.
CONTROLLING MOVEMENT OF A VEHICLE
Apparatus (101) for controlling movement of a vehicle (100), a system (201) and vehicle 5 (100) comprising the apparatus (101), and a method (500, 600) for controlling the movement of a vehicle (100) are disclosed. The apparatus (101) comprises a controller (10) configured to receive first signals from a receiving means (202) in dependence on received transmitted signals from a remote control device (200) indicating a requested motion of a vehicle and to receive second signals indicative of a value of traction of the vehicle. A maximum speed 10 value for the vehicle is determined in dependence on the value of traction of the vehicle and/or on one or both of the detected pitch and roll angles of the vehicle (100). The controller (10) provides an output signal for controlling speed of the vehicle (100) based on the requested motion. The output signal is limited dependent upon the maximum speed value determined by the controller (10).
