A control system for an electric vehicle has a vehicle speed calculation section that calculates a speed of the electric vehicle and a control unit that controls an inverter of an electric motor to provide road wheels with a predetermined reference torque in accordance with a manipulated value of an accelerator pedal, wherein the unit has a reference torque correction section that changes the reference torque from an original value and then returns the changed reference torque to the original value when a calculated speed of the electric vehicle is in a given speed range.

Torque control system for suppressing vibration in an electric vehicle

A brake control apparatus includes a vehicle sensor to sense a vehicle condition, and a control unit to start a hill hold control to hold a vehicle in a stop state by a braking force produced by a brake actuator even after an end of the driver's braking operation, in accordance with a hill hold control start adjustment parameter determined from the sensed vehicle condition. The parameter may be a variable indicative of a gradient of a road.
