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.

In some examples, a controller determines a target condition of usage of a vehicle, and selects a parameter set from among a plurality of parameter sets based on the determined target 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 transmits, to the vehicle, the selected parameter set to control a setting of the one or more adjustable elements of the vehicle.

A brake control device is applied to a vehicle including a regenerative generator. The brake control device includes a pressure adjustment unit that includes an electric pump and a pressure adjustment valve, and that adjusts adjustment liquid pressure of a pressure adjustment fluid path between the electric pump and the pressure adjustment valve; and a controller that controls the electric pump and the pressure adjustment valve.

A brake controller operates PTC when an obstacle sensor detects an obstacle ahead, a vehicle speed sensor detects a vehicle speed equal to or lower than a predetermined vehicle speed, and an operation of an accelerator pedal equal to or greater than a predetermined depression amount is detected. When detection of the obstacle ahead is lost while the PTC is operating and the PTC is to be cancelled, the brake controller operates a power limiting control if a depression operation of the accelerator pedal is detected. The power limiting control limits an engine power to cause acceleration to be lower than a requested acceleration corresponding to a depression amount of the accelerator pedal.

A vehicle control apparatus according to the present invention outputs a signal regarding a target braking/driving force for guiding a vehicle in a target traveling direction to a braking/driving controller. The signal regarding the target braking/driving force is acquired based on information regarding a running route of the vehicle and a physical amount regarding a motion state of the vehicle. The vehicle control apparatus outputs a signal regarding a steering correction torque for correcting a steering torque according to a behavior of the vehicle to a steering force controller. The signal regarding the steering correction torque is acquired based on a vehicle-body slip angle of the vehicle and the target braking/driving force.
