Electrically controlled vehicle brake system having means for controlling braking based on detected actual braking effect and determined target braking effect

摘要

An electrically controlled brake system, including a brake operating member (10), a first detector (114) for detecting an operating amount of the brake operating member, a braking device (26, 28, 42, 44, 58-64, 70, 80) for braking a wheel of a vehicle, a second detector (144) for detecting an actual braking effect provided by the braking device, and a controller (100) for controlling the braking device such that the detected actual braking effect coincides with a target braking effect which is determined on the basis of the detected operating amount. The second detector detects the actual braking effect (G) in the form of a positive value when the vehicle is running in one of a forward and a backward direction, and in the form of a negative value when the vehicle is running in the other of the forward and backward directions. The controller (100) determines a positive value as the target braking effect (GT), and controls the braking device such that an absolute value of the actual braking effect coincides with the positive value of the target braking effect.
