Abstract
A vehicle travel control apparatus includes a radar sensor, a vehicle speed controller, a hydraulic pump, a proportional solenoid valve and a brake controller. When the vehicle speed controller judges a braking situation based on information from the radar sensor, the brake controller actuates the hydraulic pump and the proportional solenoid valve based on a command from the vehicle speed controller, and controls a braking torque of wheels.
