Abstract: The present invention comprises: a first control device and a second control device that control the operation of a vehicle; a start signal output unit that outputs a start signal to the first control device and the second control device if the vehicle is in a prescribed state; an input detection unit that detects the input of the start signal to the first control device and the second control device in the state in which the start signal has been output to the first control device and the second control device by the start signal output unit; and pause signal output units that output a pause signal to the first control device and the second control device if the state in which the start signal input has been detected by the input detection unit has continued for at least a prescribed amount of time.

Abstract: A vehicle brake device includes a stroke simulator, a stroke sensor, and a brake start determination unit. The stroke simulator includes a cylinder, a piston, an orifice, and a pressure sensor. The cylinder defines a liquid pressure chamber to which a brake liquid is supplied via a fluid path. The piston slides in the cylinder by the brake liquid supplied to the liquid pressure chamber. The orifice is formed in the fluid path. The pressure sensor detects a reaction pressure. The stroke sensor is configured to detect the stroke. The brake start determination unit determines an operation of the brake operation member has been started in a case where the reaction pressure detected by the pressure sensor becomes equal to or greater than a first threshold value and the stroke detected by the stroke sensor becomes equal to or greater than a second threshold value.

Abstract: A braking control device includes: a master cylinder having a master chamber defined by a master piston; and a first pressure regulation unit having a servo chamber located on an opposite side of the master chamber and supplying a servo pressure to the servo chamber to generate a master pressure in the master chamber. The first pressure regulation unit acquires the master pressure and servo pressure and determines bottoming out of the master piston based on a comparison between the master and servo pressures. The first pressure regulation unit may make the comparison based on pressure-receiving area of the servo chamber and a pressure-receiving area of the master chamber. If the servo chamber pressure-receiving area is equal to the master chamber pressure-receiving area, the first pressure regulation unit determines bottoming out occurs when a difference between the servo pressure and the master pressure equals or exceeds a predetermined pressure.
