\n Application number: 17/534,569
\n \n Abstract:
A vehicle control system includes a target driving force calculator that calculates a target driving force of a vehicle, an arithmetic operator that calculates a request driving force and a request braking force, and a stop keeping processor that keeps the vehicle in a stopped state by increasing a brake fluid pressure so that a braking force becomes equal to or larger than a stop keeping braking force. The arithmetic operator executes a pressure pre-increasing process for pre-increasing the brake fluid pressure before a stop timing and setting, as the request driving force, a cancellation driving force for canceling a braking force for pressure pre-increase, and controls, in the pressure pre-increasing process, the request braking force so that the braking force for the pressure pre-increase is increased within a range in which the braking force does not exceed a braking force threshold smaller than the stop keeping braking force.\n

\n Application number: 17/534,115
\n \n Abstract:
A vehicle control apparatus includes a contact detector, an attitude stabilization processor, and a steering intention determining unit. The contact detector is configured to detect a contact of a vehicle with an object. The attitude stabilization processor is configured to execute an attitude stabilization control that generates a yaw moment at a vehicle body on the basis of a deviation between a target yaw rate and an actual yaw rate. The steering intention determining unit is configured to determine a presence of a driver’s intention to perform steering. The attitude stabilization processor is configured to stop the generation of the yaw moment by the attitude stabilization control or reduce the yaw moment to be generated by the attitude stabilization control, in a case where the steering intention determining unit determines that the driver’s intention to perform the steering is absent after the detection of the contact by the contact detector.\n

\n Application number: 17/534,083
\n \n Abstract:
A vehicle control apparatus configured to control a driving motor coupled to at least one wheel includes a motor controller, a vehicle speed calculator, and a vehicle speed setter. The motor controller controls the driving motor in a constant speed driving mode. The vehicle speed calculator calculates a first vehicle speed based on a rotation angle of the driving motor. The vehicle speed setter sets, as a driving speed in the constant speed driving mode, a second vehicle speed based on the first vehicle speed and a brake operation amount. The vehicle speed setter sets zero as the second vehicle speed when the brake operation amount exceeds its threshold and the first vehicle speed falls below its threshold, and sets the first vehicle speed as the second vehicle speed when the brake operation amount does not exceed its threshold r the first vehicle speed does not fall below its.\n
