Description
Technical field
The utility model discloses a kind of braking control device of E-gas self-propelled vehicle, belong to self-propelled vehicle manufacturing and motor vehicle fittings technical field.
Background technology
In present automatic transmission automotive designs, Das Gaspedal and brake pedal are independently arranged separately, be arranged in the lower right of operator's compartment, when needs refuel, chaufeur is with the right crus of diaphragm pedal of stepping on the throttle, when the needs slowing-down brake, the chaufeur right crus of diaphragm unclamps throttle and moves to brake pedal and step on brake, under this operation mode, left foot was occupied with nothing when chaufeur was driven, and right crus of diaphragm acts frequently, tired easily, when emergency situation took place, because chaufeur need move on to right crus of diaphragm brake pedal and often cause drag untimely from Das Gaspedal, perhaps chaufeur was owing in a great rush throttle being got into an accident when braking to floor suddenly, if at this time there is a cover assist brake control setup left foot below, left foot is stepped on the assist brake control setup when urgent, in the time of the device brake no matter where Das Gaspedal all can disconnect throttle and keep engine idling operation, the then greatly safety and the traveling comfort of degree raising motor vehicle driving.
Equally, present instructional car, coach's auxiliary brake has only brake function, can not control throttle, need to stop immediately as student's mis-accelerator pressing (throttle is when braking) or chance emergency situation, flurried middle student is not put as still slamming throttle, continuation is to engine oil, the coach can only touch on the brake, and can't control throttle, and vehicle can not in time stop and be prone to accidents.
At above practical problems, design a kind of no matter Das Gaspedal can disconnect throttle simultaneously and keep the braking control device of engine idling operation very necessary when where braking.
Summary of the invention
Self-propelled vehicle for charged electronic throttle, the utility model provides a kind of braking control device, the function of this device is (to disconnect the accelerator pedal position sensor signal no matter Das Gaspedal can disconnect throttle simultaneously when where braking, the accelerator open degree signal transfers zero aperture signal to, together following) and keep engine idling operation, recover the control of accelerator pedal position sensor signal behind the releasing of brake control setup.This device can be contained in automatic transmission vehicle cab lower left, left foot auxiliary brake as the automatic transmission vehicle, keep original right crus of diaphragm brake gear, do not change original right crus of diaphragm and control the operating habit of throttle and brake simultaneously, in case of emergency, also disconnect throttle and driving engine simultaneously by the left foot assist brake and keep idling; This device also can be merged into a cover brake gear with the original brake of automatic transmission vehicle, realizes that left foot (or right crus of diaphragm) brake disconnects throttle simultaneously and driving engine keeps idling, the left and right sides pin steer mode of right crus of diaphragm (or left foot) control throttle; This device also can be contained in the copilot chamber of automatic transmission or manual vehicle, as coach's auxiliary brake.
The E-gas of self-propelled vehicle is the significant components of electric injection system, mainly form by parts such as pedal, sensor and wire harness, sensor divides by its principle of work Hall element and potentiometer pick-off two big classes usually, design dual sensor loop (redundancy), loop or single-sensor loop, sensor loop at above different types, the utility model adopts same technical scheme, only changes that different wiring just can realize no matter Das Gaspedal can disconnect throttle simultaneously and keep engine idling operation when where braking.
The technical scheme that the utility model adopted is: as shown in Figure 1, connect with accelerator pedal position sensor (6) to the loop of control unit of engine (8) with one pair of normally closed contact of the travel switch (2) of brake pedal (1) interlock, one pair of open contact then links to each other with voltage divider (4), and another pair open contact is used to control stoplight stop lamp; One pair of normally closed contact of travel switch (3) is connected with accelerator pedal position sensor (7) to the loop of control unit of engine (8), and one pair of open contact then links to each other with voltage divider (5), and another pair open contact is used for the switching in Idle Switch loop.
When brake pedal (1) when not being operated, deliver to two sensors (6) (7) of the accelerator open degree signal of control unit of engine (8) from Das Gaspedal; When brake pedal (1) when being operated, the accelerator open degree signal of delivering to control unit of engine (8) switches to throttle zero aperture signal from voltage divider (4) (5) representative by the signal of two sensors of original Das Gaspedal (6) (7), stoplight stop lamp (9) is lighted simultaneously, Idle Switch (10) loop is connected, this moment no matter Das Gaspedal where, brake of motor-driven vehicle braking, control unit of engine (8) stop throttle and quicken to refuel and keep engine idling operation.
The above wiring is used for the E-gas of double loop (redundancy) sensor, when E-gas is single-sensor, wiring cancellation between travel switch (3) and accelerator pedal position sensor (7) and the voltage divider (5), voltage divider (5) changes stand-by facility into, and concrete wiring as shown in Figure 2.
The beneficial effects of the utility model are: in case of emergency, no matter Das Gaspedal in which position, disconnects throttle and keeps engine idling operation when all can realize brake by the utility model, thereby reach the purpose of safe driving.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is further specified.
Fig. 1 is the schematic diagram that the utility model is used for dual sensor loop E-gas.
Fig. 2 is the schematic diagram that the utility model is used for single-sensor loop E-gas.
