A vehicle brake system installed on a vehicle equipped with an electric motor that applies a drive force to a wheel, including: a brake device configured to apply a braking force to the wheel; and a brake controller configured to control the braking force, wherein the brake controller is configured to execute a swinging-back reducing control for reducing swinging-back of a body of the vehicle on stopping by weakening the braking force immediately before the vehicle stops, based on a motor-rotation-speed-dependent running speed that is a running speed of the vehicle detected in dependence on a rotation speed of the electric motor.

A vehicle control device includes a controller configured to control operation of a braking device and operation of a driving motor. The controller can switch between a normal mode of controlling acceleration/deceleration in accordance with a driver's acceleration/deceleration operation, and a cruise control mode of maintaining the vehicle speed at a target speed without being dependent on the acceleration/deceleration operation. The controller is configured to execute braking control, including braking by the braking device and regenerative braking by the driving motor, during the cruise control mode in accordance with a change in a vehicle traveling condition. The braking control includes causing the braking device to generate a braking force without using the regenerative braking and subsequently executing a braking-force switching process including increasing a braking force by the regenerative braking while reducing the braking force from the braking device, if a determination result indicates that the vehicle speed is stable.

A vehicle control device includes a motor control unit, a turning control unit, and a turning information detection unit. The motor control unit controls electric motor. The turning control unit controls a turning device. The vehicle control device, by the motor control unit controlling the electric motor and the turning control unit controlling the turning device when the turning information detection unit detects information related to turning of the wheels, controls a turning force as a force to be applied to the tire of the wheel in order to turn the vehicle.

A virtual manual transmission system for an electric vehicle for simulating the behavior of a vehicle having a manual transmission by controlling a motor while protecting an electric storage device. A controller is configured to: change torque of the motor when a virtual manual shifting is executed by operating a clutch device, an accelerator device, and a shifting device; and reduce a regulation on a change rate of the torque of the motor or an input/output power to/from the electric storage device.

A weight profile determination system may be provided that includes a sensor and a controller. The sensor may be disposed along a route and configured to generate a plurality of force measurements of a vehicle system moving on the route relative to the sensor. The force measurements may be obtained at different times and correspond to different locations along a length of the vehicle system. The controller may determine a weight profile for the vehicle system based on the force measurements generated by the sensor. The weight profile can represent a distribution of weight along the length of the vehicle system. The controller may communicate the weight profile to one or more of the vehicle system or an offboard device for controlling movement of the vehicle system based on the weight profile.
