Accident or vehicle, which are absorbed in road surface, to extricate oneself.
Automatically the technology of starting to walk is mainly simple slope starting miscellaneous function to existing commercial car, it is impossible to which satisfaction has cross-country
The starting demand of the commercial car of performance requirement.
Utility model content
The utility model aim is to provide a kind of automatic start control device of commercial car, and commercial car can be realized various
Smooth starting under road conditions.
The utility model solves technical problem and adopts the following technical scheme that：A kind of automatic start control device of commercial car,
The Slope Transducer being connected including entire car controller and with the entire car controller signal, start to walk automatically switch, brake pedal
Switch, park brake switch, accelerator pedal sensor and vehicle speed sensor；
The road gradient signal transmission that the Slope Transducer is detected is to the entire car controller；
The automatic starting is switched automatic start request signal transmission to the entire car controller；
The brake pedal switch is by braking state signal transmission to the entire car controller；
The park brake switch is by parking braking status signal transmission to the entire car controller；
Acceleration pedal position signal is transmitted to the entire car controller by the accelerator pedal sensor；
Speed signal is transmitted to the entire car controller by the vehicle speed sensor；
The entire car controller is according to road gradient signal, automatic start request signal, braking state signal, parking braking
Status signal, acceleration pedal position signal and speed signal and the engine speed gathered by CAN bus, engine are defeated
Go out torque and current gear, entire car controller is to anti-lock braking system, automatic driven management system, automatic transmission control system
System and engine management system are controlled, and realize the automatic starting control of vehicle.
The utility model has the advantages that：Pass through the automatic start control device of the commercial car of the utility model, energy
It, can be in starting-up process between automatic locking rear axle wheel enough according to road gradient situation adjust automatically to the moment of torsion control of engine
Differential lock can control abs braking power size, disclosure satisfy that driver need not step on oil to improve commercial car starting performance
Door pedal can be achieved with the requirement of vehicle start.
Description of the drawings
Fig. 1 is the structure diagram of the automatic start control device of commercial car of the utility model；
Specific embodiment
The technical solution of the utility model is further elaborated with reference to embodiment and attached drawing.
Embodiment 1
Present embodiments provide a kind of automatic start control device of commercial car, including entire car controller (VCU) and with institute
State the Slope Transducer of entire car controller signal connection, automatic start to walk switch, brake pedal switch, park brake switch, acceleration
Pedal sensor and vehicle speed sensor.
The road gradient signal transmission that the Slope Transducer is detected is to the entire car controller；
The automatic starting is switched automatic start request signal transmission to the entire car controller；
The brake pedal switch is by braking state signal transmission to the entire car controller；
The park brake switch is by parking braking status signal transmission to the entire car controller；
Acceleration pedal position signal is transmitted to the entire car controller by the accelerator pedal sensor；
Speed signal is transmitted to the entire car controller by the vehicle speed sensor；
The entire car controller is according to road gradient signal, automatic start request signal, braking state signal, parking braking
Status signal, acceleration pedal position signal and speed signal etc., and engine is included by CAN bus acquisition and runs shape
The information such as state, AT operating statuses, for example, engine speed, engine output torque and current gear etc..According to information above,
VCU handle and calculate in real time, and ABS, ADM, TCU and EMS are controlled, to realize the automatic starting control of vehicle.
Wherein, anti-lock braking system (ABS) sends brake request for responding VCU, to realize braking operation or releasing.
Automatic driven management system (ADM) is used for the differential lock control data that corresponding VCU is sent, to realize to differential lock
Locking and releasing ensure the starting performance of vehicle.
Automatic transmission control system (TCU) sends automatic transmission (AT) operating status and is used for vehicle start shape to VCU
State judges, receives and responds the gear request of VCU transmissions.
Engine management system (EMS) sends engine operating state to VCU for vehicle start condition adjudgement, receives simultaneously
Respond moment of torsion control and the rotating speed limitation request that VCU is sent.
The automatic start control device of commercial car through this embodiment, can be according to road gradient situation adjust automatically to hair
The moment of torsion control of motivation, can in starting-up process between automatic locking rear axle wheel differential lock to improve commercial car starting performance, energy
It is enough that abs braking power size is controlled, it disclosure satisfy that driver's pedal that need not step on the throttle can be achieved with the requirement of vehicle start.
Moreover, the utility model has been applied to a cross-country commercial car of vapour type, in the asphalt road of 29% gradient, from driver
Releasing of brake pedal begins with the speed time as 3.9s to vehicle, and setting speed is reached from releasing of brake pedal to vehicle
(6.5km/h the starts to walk successfully automatically) time is 4.7s, and starting process is steadily quick.
The sequencing of above example only for ease of description, does not represent the quality of embodiment.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：
It still can modify to the technical solution recorded in foregoing embodiments or which part technical characteristic is carried out etc.
With replacement；And these modifications or replacement, the essence of appropriate technical solution is not made to depart from various embodiments of the utility model technology
The spirit and scope of scheme.
