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

An electrically controlled brake system for a wheel of a vehicle, comprising:

• a brake operating member;
• first detecting means for detecting an operating amount of said brake operating member;
• braking means for a one of reducing rotational speed and preventing rotation of said wheel to produce a braking effect;
• second detecting means for detecting an actual braking effect provided by said braking means;
• primary control means for controlling said braking means such that said actual braking effect detected by said second detecting means coincides with a target braking effect determined on the basis of said operating amount of said brake of said brake operating member detected by said first detecting means;
• and
• auxiliary control means operable when said vehicle is in a stop state, said auxiliary control means inhibiting said primary control means and controlling said braking means such that an operating force of said braking means is directly taken from said operating amount of said brake operating member detected by said first detecting means to preclude an unnecessarily large braking force being applied to the wheel when said vehicle is in the stop state.

An electrically controlled brake system for a wheel of a vehicle, comprising:

• a brake operating member;
• first detecting means for detecting an operating amount of said brake operating member;
• braking means for braking said wheel;
• second detecting means for detecting an actual braking effect provided by said braking means, said second detecting means detecting said actual braking effect in the form of a positive value when said vehicle is running in one of a forward direction and a backward direction, and in the form of a negative value when said vehicle is running in the other and said forward and backward directions;
• primary control means for determining a positive value as a target braking effect on the basis of said operating amount detected by said first detecting means, and controlling said braking means such that an absolute value of said actual braking effect detected by said second detecting means coincides with said positive value of said target braking effect;
• and
• auxiliary control means for inhibiting said primary control means for controlling said braking means based on said actual braking effect when said vehicle is in a stop state.
