Abstract
The invention discloses a kind of automatic braking control system for preventing automobile from crashing during reversing, comprise: engine management system, electric stabilizing system controller, gearbox control system, Reverse Sensor controller and Reverse Sensor, carry out communication by the CAN bus between above-mentioned a plurality of parts, by the Reverse Sensor controller, carry out automatic backing.Wherein, distance detection when Reverse Sensor is moveed backward sends to the Reverse Sensor controller with detected signal, by sending signal to the CAN network after the computing of Reverse Sensor controller.The electric stabilizing system controller receives the signal that the Reverse Sensor controller sends to the CAN bus, two trailing wheels or two front-wheels is carried out gradual braking stop up to automobile.Because the automobile major part is equipped with ESP system and reverse radar system now, therefore can realize function of the present invention by simply installing additional, thereby cost is lower, can improve the safety of reversing, reduce user's loss and danger, improve the traveling comfort, intelligent of car load simultaneously.
Description
Technical field
The invention belongs to field of automobile control, particularly relate to a kind of control system that bumps when preventing reversing automobile.
Background technology
Along with the continuous development of transportation, the driver need take the operation in each orientation into account comprehensively, and difficulty strengthens, and finds in time during reversing that the back obstacle is one of them.Now for the trouble and worry of eliminating chaufeur, the safety and the accuracy aspect of improve reversing, stopping, the reversing automobile technology is significantly improved, present reverse radar system is installed on all automobiles substantially, not only can report to the police can also range of a signal, but for new hand, can not in time brake the appearance of collision problem still to occur moveing backward.Simultaneously when on bevelled is domatic, moveing backward, in the time of can't falling upward slope because the idling of automobile is crossed low, can only make by open the throttle wide and pour into the position, and the driver just can not very fast timely brake avoids the possibility of moveing backward on the slope and bumping at this moment.
Summary of the invention
The present invention is for avoiding the appearance of above-mentioned reversing collision, and the distance that monitors by Reverse Sensor, control electric injection system and brake system, automobile is carried out the function of automatic backing and brake, avoid when moveing backward, possibility of collision occurring, thereby reach loss and the danger that reduces collision and bring at special road section or new hand driver.
The invention discloses a kind of automatic braking control system for preventing automobile from crashing during reversing, comprise: engine management system, electric stabilizing system controller, gearbox control system, Reverse Sensor controller and Reverse Sensor, carry out communication by the CAN bus between above-mentioned a plurality of parts, by the Reverse Sensor controller, carry out automatic backing.
Wherein, distance detection when Reverse Sensor is moveed backward sends to the Reverse Sensor controller with detected signal, by sending signal to the CAN network after the computing of Reverse Sensor controller.The electric stabilizing system controller receives the signal that the Reverse Sensor controller sends to the CAN bus, two trailing wheels or two front-wheels is carried out gradual braking stop up to automobile.
Further, electric stabilizing system controller Control of Automobile makes it stop from object 30cm distance.
Can not reduce when backing distance occurring, and engine management system slowly improves rotating speed by gearbox control system notice driving engine when receiving astern signal, up to normally moveing backward, and then the control of moveing backward.
Further, described Reverse Sensor controller is integrated in the car body controller.
Control system of the present invention also comprises a switch, is used for controlling the operation of Reverse Sensor controller, can close this controller when not needing this function.
The present invention utilizes CAN (Body Control network) bus and automobile electronic fuel oil jet system, ESP system to carry out communication by the function of the measurement reversing spacing that utilizes Reverse Sensor itself and have, reaches at suitable time open the throttle wide and suitable time and brakes.
The present invention has the following advantages:
1. cost is lower, and the automobile major part is equipped with ESP system and reverse radar system now.
2. improve the safety of reversing, reduce user's loss and danger.
3. can when reversing place road conditions are relatively poor, also can finish reversing smoothly.
4. under the prerequisite that does not raise the cost, improve the traveling comfort, intelligent of car load.
Description of drawings
Fig. 1: system schematic of the present invention;
Fig. 2: another embodiment scheme drawing of system.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is specifically described.
As shown in Figure 1, automatic braking control system for preventing automobile from crashing during reversing of the present invention comprises: engine management system, electric stabilizing system controller, gearbox control system, Reverse Sensor controller and Reverse Sensor, carry out communication by the CAN bus between the above-mentioned parts.
Distance detection when Reverse Sensor is moveed backward sends to the Reverse Sensor controller with detected range signal, by sending signal to the CAN network after the computing of Reverse Sensor controller.When the driver steps on brake, hang reverse gear, then during releasing of brake, the Reverse Sensor controller is started working, Reverse Sensor is measured the object of car back and the distance of automobile, automobile begins automatic backing, when reaching certain value, distance (can set this value as requested, as 30cm), electric stabilizing system controller ESP receives the signal that the Reverse Sensor controller sends to the CAN bus, electric stabilizing system controller ESP begins that then two trailing wheels or two front-wheels are carried out gradual braking and stops (in order to increase traveling comfort up to automobile, brake function needs to realize gradually), make car stopping of setting in earlier stage, stepping on brake at last and hanging neutral, finish this function from object 30cm distance.
When backing distance occurring and can not reduce, that is to say the slope or when being absorbed in poor highway section of to occur moveing backward, when this moment, control unit of engine ECU received this signal, then slowly improve rotating speed by gearbox control system TCU notice driving engine, up to normally moveing backward, automobile can be finished reversing by above-mentioned steps then.
As shown in Figure 2, the Reverse Sensor controller also can be integrated in car body controller BCM, convenient installation, maintenance, management and control.
Can increase a switch and control the operation of Reverse Sensor controller, when not needing this function, can close this controller.
Claims (7)
