Abstract

PURPOSE:To extremely facilitate the crawling go-astern such as when entering a car into a garage by releasing a brake lock during the go-astern of the car by means of the action of a reverse switch detecting the reverse shift position of a speed changer. CONSTITUTION:A lock condition judging circuit 14 judges predetermined condition by means of input signals from various sensors and outputs a control signal to a self-hold circuit 12, which, on receiving this signal, activates a solenoid brake 10 to lock a foot brake. In order to release this brake lock, a release signal is fed from an OR gate 6 to the self-hold circuit 12. Signals from an acceleration switch and parking switch as well as a brake lock release signal from a reverse switch 18 are fed to this OR gate 6. This reverse switch 18 is turned on when the speed changer of the car is transferred to a reverse shift position.

時に前記ブレーキロックが解除される。In this type of brake lock device, the locking action is configured such that the braking state is locked and maintained by an electromagnetic solenoid under a predetermined condition, such as when the foot brake is applied and the vehicle speed drops below a predetermined value. When the vehicle starts from a brake locked state, the brake lock is released by operating the accelerator, and the brake lock is released when a main parking braking operation such as a parking brake or a shift operation to the parking position of an automatic vehicle is performed. .

点が生じていた。As described above, with this type of brake lock device, the brake lock is activated when the vehicle speed drops below a certain value while the brakes are being applied, and it is possible to provide a device with extremely excellent operability when the vehicle is moving forward. In some cases, the brake lock becomes a hindrance when the vehicle moves backward. For example, when reversing a vehicle when entering a garage, it is necessary to reverse the vehicle at a very slow speed.In a manual transmission vehicle, the brake and accelerator are normally operated alternately, and in an automatic vehicle, the brake is normally adjusted slightly. In such a case, when the aforementioned brake lock is activated, the lock must be released by operating the accelerator each time, resulting in an extremely complicated operation.

ロック装置を提供することにある。The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide an improved brake locking device that releases the brake lock when the vehicle is reversing, such as when parking the vehicle in a garage, thereby enabling the vehicle to reverse at a very slow speed. There is a particular thing.

ックする。The action of the self-hold circuit 12 is controlled by a control signal from a lock condition determination circuit 14, and determines a predetermined condition based on signal input from various sensors installed in the vehicle. ,
When wheel lock occurs, that is, a state in which the wheels are locked and the wheels and the road surface slip even though the vehicle body does not stop, the control signal is sent from the determination circuit 14 to the self-hold circuit 12 after the vehicle speed decreases below a predetermined value. This excites the electromagnetic brake 10 and locks the foot brake.

従って、このブレーキロック状態では、もはや運転者が
