CONTROL DEVICE, CONTROL METHOD AND NON-TRANSITORY STORAGE MEDIUM
A control device includes: an acquisition unit configured to acquire, from a driving assist system, a requested acceleration and ending information indicating an end of a deceleration control; and a control unit configured to control a powertrain and a brake based on the requested acceleration, and perform a prescribed process of stabilizing a driving force and a braking force that are generated in an ending process of the deceleration control based on the requested acceleration when the acquisition unit acquires the ending information.
Rider selectable ride comfort system for autonomous vehicle
An autonomous mode controller of an autonomous vehicle according to various rider-selectable comfort configurations. When the controller identifies a comfort configuration, it will access a configuration data set that corresponds to the selected comfort configuration. The controller also will receive sensor data from one or more autonomous driving sensors. In response to the received sensor data, the controller will generate an instruction for operation of a steering, braking, powertrain or other subsystem for operation of the autonomous vehicle. The instruction while includes values that correspond to the sensed data and to one or more parameters of the configuration data set. The subsystem will then cause the autonomous vehicle to move according to the instruction.
Single pedal configuration for engine speed control and vehicle braking control
A vehicle controller may determine a decelerator input associated with controlling an engine speed of an engine of the vehicle. The vehicle controller may determine, while the vehicle is moving and based on the decelerator input satisfying a braking threshold, that an engine decelerator, associated with the decelerator input, is to be enabled for use in stopping the vehicle. The vehicle controller may determine, based on determining that the engine decelerator is to be used to cause the vehicle to be stopped, an amount of braking to be applied by a braking device of the vehicle to stop the vehicle. The vehicle controller may automatically cause the braking device to apply the amount of braking to stop the vehicle.
DRIVING ASSIST SYSTEM, VEHICLE WITH SELF-DRIVING CAPABILITY, AND DRIVING ASSIST METHOD
An automated-parking control unit prevents a brake noise during braking, when causing a vehicle to start moving forward or backward. The automated-parking control unit includes: an environment recognizer to recognize environment of a vehicle; a behavior controller to execute behavior control inclusive of steering and acceleration/deceleration, based on recognized information; a brake hold instructor to suspend the vehicle with the behavior control and hold the suspension until receiving behavior-related operation by a driver; and a brake fluid pressure controller, when the vehicle is made to start moving forward or backward, to estimate a range having a brake noise and increase a change rate of a brake fluid pressure in a brake-noise range having a brake noise, as compared with that in a no-brake-noise range.
SYSTEM, METHOD, AND APPARATUS FOR OPERATING A HIGH EFFICIENCY, HIGH OUTPUT TRANSMISSION
A transmission includes an input shaft and an output shaft, the input shaft selectively accepting a torque input from a prime mover, and the output shaft selectively providing torque output to a driveline. A controller determines a shaft displacement angle representing an angle value of rotational displacement difference between at least two shafts of the transmission, and performs a transmission operation responsive to the shaft displacement angle.
High efficiency, high output transmission
A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.
Automatic downhill snub braking
Methods and apparatus are disclosed herein that perform automatic downhill snub braking. An example apparatus disclosed herein includes an electronic powertrain controller to cause a deceleration of a vehicle in response to a first request from an electronic cruise controller, the first request responsive to a change in grade of a driving surface and an electronic brake controller to apply snub braking to the vehicle in response to a second request received from the electronic cruise controller, the second request responsive to a speed of the vehicle reaching a maximum speed.
Vehicle stability control system and method
A vehicle stability control system and a vehicle stability control method which are capable of more improving lateral stability of a vehicle when the vehicle is turning on a descent inclined road, may enable the vehicle to turn along a turning trace intended by a driver through cooperative control of active front steering (AFS) control and an electronic stability control (ESC) when the vehicle is turning on the descent inclined road.
CONTROL METHOD OF REDUCING A STEERING LOAD OF AN IN-WHEEL MOTOR VEHICLE
A control method of an in-wheel motor vehicle includes: determining, by a controller, a state of a steering load that is a load of a steering system; maintaining, by the controller, a front wheel brake in a released state, when the state of the steering load is in a high load state of a predetermined level or more; determining, by the controller, a tire angle of a front wheel according to a driver steering input based on driver steering input information in the released state of the front wheel brake; determining, by the controller, a required tire rotational angle of the front wheel by using the determined tire angle of the front wheel; and reducing, by the controller, the steering load by driving an in-wheel motor of the front wheel for a compensation by the determined required tire rotational angle of the front wheel.
BRAKING CONTROL METHOD ACCORDING TO FRICTION OF ROAD SURFACE
A braking control method according to friction of road surface includes computing a real-time wheel speed according to a signal received from a wheel speed sensor; storing the real-time wheel speed as a wheel initial velocity when a braking event occurs; determining a relative-peak value according to the real-time wheel speed; estimating a vehicle deceleration according to the relative-peak value and the wheel initial velocity; computing an adjustment parameter according to the vehicle deceleration and a tire slip threshold, wherein the adjustment parameter reflects friction coefficient of road surface; and adjusting time length of an enhancement stage in an enhance-pressure control period of a stepped pressure-increasing phase according to the adjustment parameter; or adjusting time length of a reduction stage in a reduce-pressure control period of a stepped pressure-decreasing phase according to the adjustment parameter.
