In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of device that prevents vehicle start-backing when ascending, it comprises brake pedal, micro-control unit, power-transfer clutch and two-position inductor, described two-position inductor is installed on the described brake pedal, whether respond to the residing ad-hoc location of described brake pedal is brake control power and gradient resistance balance position, if, then the signal with the residing ad-hoc location of brake pedal sends to described micro-control unit, and described micro-control unit makes power-transfer clutch carry out binding operation.
A kind of method that prevents vehicle start-backing when ascending, it may further comprise the steps: utilize the two-position residing ad-hoc location of inductor induction brake pedal whether to be in brake control power and gradient resistance balance position, if then the signal with the residing ad-hoc location of brake pedal sends micro-control unit to; Receive this ad-hoc location signal, micro-control unit makes power-transfer clutch carry out binding operation according to this ad-hoc location signal at once, and driving engine is given the automatic transmission with hydraulic torque converter output torque, makes vehicle start.
Adopt technique scheme, in conjunction with the following embodiment that will describe in detail, beneficial technical effects of the present invention is: the present invention prevents that the device of vehicle start-backing when ascending from comprising the two-position inductor, whether the two-position residing ad-hoc location of inductor induction brake pedal is in brake control power and gradient resistance balance position, and with this position as equilibrium point control vehicle upward slope safe starting, it is simple in structure, easy installation and removal, the present invention prevents that the device of vehicle start-backing when ascending from utilizing two-position inductor and micro-control unit, prevent retreating of vehicle driving up startup, this method reduces the danger of driving, and reduces the generation of traffic accident.
Also the present invention is described in further detail in conjunction with the accompanying drawings below by the specific embodiment.
Description of drawings
Fig. 1 is the constructional drawing that prevents the device of vehicle start-backing when ascending of the present invention.
Fig. 2 is the diagram of circuit that prevents the vehicle start-backing when ascending method of the present invention.
The specific embodiment
Also the present invention is described in further detail in conjunction with the accompanying drawings below by specific embodiment.
Be the constructional drawing that prevents the device of vehicle start-backing when ascending of the present invention as shown in Figure 1.This device comprises that (English full name is: Micro Control Unit for a two-position sensor 1, a brake pedal 2 and a micro-control unit 3; English abbreviation is: MCU) and a power-transfer clutch 4.This brake pedal 2 has A, B, C and four positions of D.These brake pedal 2 residing physical slots when the representative of A position is not stepped on this brake pedal 2; B represents the position enable position of braking signal switch, and promptly this brake pedal 2 stoplight stop lamp when being lower than the B position is activated, and this brake pedal 2 stoplight stop lamp when being higher than the B position is closed; C represents the position brake control power and gradient resistance balance position, promptly this brake pedal 2 when being lower than the C position brake weight greater than gradient resistance, this brake pedal 2 when being higher than this C position brake weight less than gradient resistance; Position when on behalf of brake pedal 2, D the position be trampled to death.This two-position sensor 1 is installed on this brake pedal 2, to judge these brake pedal 2 residing ad-hoc locations and this position signal is issued this micro-control unit 3.This micro-control unit 3 stores specific program, and this specific program can be that the C position is as equilibrium point control vehicle upward slope safe starting through brake control power and gradient resistance balance position according to brake pedal 2.
Brake control power and gradient resistance balance position are determined by following method: the vehicle that automatic transmission with hydraulic torque converter will be housed is parked in 30% ramp, and (it is wide that experiment records the location application scope that records on 30% ramp, also can select the ramp of other gradients as required for use) on, the brake pedal 2 that has been operated is slowly lifted; Start vehicle, with vehicle by the position of static brake pedal 2 during to the transformation point that moves as brake control power and gradient resistance balance position, i.e. C position.
Described automatic transmission with hydraulic torque converter is an electric control mechanical type automatic speed variator.
This principle of work that prevents the device of vehicle start-backing when ascending is: when vehicle on up gradient during by static starting, brake pedal 2 slowly moves to the C position from the D position, in this process, brake weight is greater than gradient resistance, vehicle can not retreat; When brake pedal 2 surpasses the C position, vehicle will be drawn back, but two-position inductor 1 can be sensed brake pedal 2 and sends signal by the C position and to micro-control unit 3; Micro-control unit 3 makes power-transfer clutch 4 carry out binding operation at once, and driving engine is given the automatic transmission with hydraulic torque converter output torque, makes vehicle start, to realize stoping the function of vehicle start-backing when ascending.
Be the diagram of circuit that prevents the vehicle start-backing when ascending method of the present invention as shown in Figure 2, it may further comprise the steps:
Step 200: utilize inductor 1 induction brake pedal 2 in two-position whether to move up from the D position;
Step 210: sense brake pedal 2 and do not move up from the D position, two-position inductor 1 is carried out other operations;
Step 220: sense brake pedal 2 and move up, when brake pedal 2 process C positions, send this position signal to micro-control unit from the D position;
Step 230: receive this position signal, micro-control unit 3 makes power-transfer clutch 4 carry out binding operation at once, and driving engine is given the automatic transmission with hydraulic torque converter output torque, makes vehicle start.
In the above embodiment of the present invention, the device that prevents vehicle start-backing when ascending comprises a pair of position sensor 1, this two-position inductor 1 also can be put the inductor agency with two units, it responds to brake pedal 2 residing diverse locations respectively, and these position signals are sent to micro-control unit 3.
In another embodiment of the present invention, two-position inductor 1 can be responded to any one position (removing the C position) of A, B, C and four positions of D that brake pedal 2 has, and send the signal of brake pedal 2 residing positions to micro-control unit 3, micro-control unit 3 is according to the position signal that receives, make power-transfer clutch 4 carry out binding operation at once, driving engine is given the automatic transmission with hydraulic torque converter output torque, makes vehicle start.The cooresponding vehicle start-backing when ascending method that prevents of present embodiment is also done corresponding change, and these changes are conspicuous to those skilled in the art.
