US 8,897,984 B2 · Braking force generator

Abstract

The object of the present invention is to provide a braking force generator capable of preventing a braking force from varying, even if an ON signal of an IG switch is not transmitted. The braking force generator includes a hydraulic pressure generation unit that becomes in an operation state according to an ON state of the IG switch of a vehicle or an opening and closing operation of an opening and closing member of the vehicle and generates a braking force according to an electrical signal based on an operation amount of a driver, and a conditional stop unit that puts the hydraulic pressure generation unit in an operation stop state if an OFF state of the IG switch continues for a predetermined time after the hydraulic pressure generation unit becomes in the operation state according to the opening and closing operation of the opening and closing member.

Dependent claims

A braking force generator comprising:

a hydraulic pressure generation unit that becomes in an operation state according to an ON state of an ignition switch of a vehicle or an opening and closing operation of an opening and closing member of the vehicle, and generates a braking force according to an electrical signal based on an operation amount of a driver;
and
a conditional stop unit that puts the hydraulic pressure generation unit in an operation stop state if an OFF state of the ignition switch continues for a predetermined time after the hydraulic pressure generation unit becomes in the operation state according to the opening and closing operation, wherein
the conditional stop unit puts the hydraulic pressure generation unit in the operation stop state if it is determined that the ON state cannot be obtained, even if the opening and closing operation is obtained.
