Hill start control device suitable for AMT (Automated Mechanical Transmission) and use method thereof

Abstract

The invention discloses a hill start control device suitable for an AMT (Automated Mechanical Transmission), which comprises an air storage tank sequentially connected with an air circuit of a spring air chamber via a one-way valve, a handbrake control valve, a differential relay valve and a hill start solenoid valve; meanwhile, an air pressure sensor arranged between the handbrake control valve and the differential relay valve is connected with a circuit of an entire car electronic controller; and the entire car electronic controller is also in circuit connection with an engine, a gear box, a hill start switch and an audible and visual alarm. When used, the handbrake control valve is switched on to conduct the air circuit between the air storage tank and the hill start solenoid valve; then the hill start solenoid valve is controlled according to an air pressure signal and an engine torque by the entire car electronic controller; and the hill start solenoid valve is controlled to charge the spring air chamber when the engine torque achieves a preset valve so as to release the brake step by step so that a safe hill start is fulfilled. The design has the advantages of low operating difficulty and wide range of application, as well as high security and strong flexibility.

Description

technical field [0001] The invention relates to a hill start control device for automobiles, in particular to a hill start control device suitable for AMT vehicles and a method for using the same, and is particularly suitable for preventing a vehicle equipped with an automatic transmission AMT from slipping when starting on a hill slope back. Background technique [0002] At present, when a car is started on an uphill, there is often a dangerous situation that the vehicle slips and retreats, resulting in traffic accidents. In order to avoid backing up when starting on a hill, various hill start control methods shown below have emerged. [0003] When a car with manual transmission starts uphill: the driver must master a series of operating steps such as the clutch pedal, the accelerator pedal and the hand brake control valve, that is, first half-engage the clutch while increasing the engine throttle, and then release it when the car is about to start. Only by handbraking can...
