Description
Technical field
The invention belongs to vehicle cruise technical field, and in particular to a kind of intelligent vehicle constant speed cruising system.
Background technology
Constant speed of vehicle cruise system is the device of constant speed of vehicle traveling, vehicle is once set cruise for regulation speed
State, engine oil amount is just controlled by Engine ECU (control unit of engine), Engine ECU can according to road condition and
The running resistance of automobile constantly adjusts fuel delivery, vehicle is travelled in the speed of setting all the time.
Vehicle, due to vehicle inertia and Action of Gravity Field, is under minimum state in descending in the fuel delivery of engine
Uncontrollable speed continues to increase.Especially vehicle heavy duty and the gradient it is larger when, it is easier to occur speed it is uncontrollable cruise
The phenomenon of speed.
The content of the invention
It is an object of the invention to provide a kind of intelligent vehicle constant speed cruising system, solve vehicle heavy duty and the gradient is larger
When, it is susceptible to the uncontrollable technical problem in cruise speed of speed.
The technical scheme is that, a kind of intelligent vehicle constant speed cruising system, it is characterized in that：The constant speed cruising system bag
Include engine control module, vehicle speed sensor, retarder and retarder control module.
Vehicle speed sensor is fixed on vehicle gear box, vehicle speed sensor collection GES, and GES is transmitted
To combined instrument for vehicle；Combination instrument on vehicle carries out data processing to the GES for receiving, and calculates and obtain vehicle reality
Border speed, and actual vehicle speed is transferred to engine control module and retarder control module by vehicle power CAN；It is slow
Fast device control module is according to patrolling that the enabling signal of constant speed continuation of the journey switch, engine control module on reception vehicle instrument desk send
Boat vehicle speed value and actual vehicle speed, judge whether to need to carry out vehicle braking, if that is, actual vehicle speed is needed higher than cruise vehicle speed value
Brake, and braking instruction is sent to retarder, retarder performs deceleration；
Engine control module receives the enabling signal and cruise vehicle speed value of constant speed continuation of the journey switch on vehicle instrument desk, starts
Whether machine control module judges actual vehicle speed less than cruise speed, if actual vehicle speed is less than cruise speed, engine control
Module control engine realizes cruise speed；Retarder is fixed on gearbox, the input shaft of retarder and the output of gearbox
Axle is fixedly connected, and the output shaft of retarder is fixedly connected with vehicular transmission shaft.
The beneficial effects of the invention are as follows, the present invention voluntarily adjusts speed and reaches cruise purpose according to the actual road conditions of vehicle,
Compensate for original cruise system cannot realize the defect of cruise in descending；Using constant speed cruising system of the invention, department
Machine controls gas pedal without going again, because speed is required and control braking of slowing down beyond cruise, is alleviated without in descending
Driving fatigue, while reducing unnecessary speed change, can save fuel.
Brief description of the drawings
Fig. 1 is a kind of composition block diagram of intelligent vehicle constant speed cruising system of the invention.
Specific embodiment
Technical scheme is described in further detail with reference to Figure of description.
As shown in figure 1, a kind of intelligent vehicle constant speed cruising system of the invention includes that engine control module, speed are sensed
Device, retarder and retarder control module.
Vehicle speed sensor is fixed on vehicle gear box, vehicle speed sensor collection GES, and GES is transmitted
To combined instrument for vehicle.
Combination instrument carries out data processing to the GES for receiving, and vehicle actual vehicle speed is calculated and obtain, by actual car
Speed is transferred to engine control module and retarder control module by vehicle power CAN.
Retarder control module controls mould according to the enabling signal of constant speed continuation of the journey switch, engine on vehicle instrument desk is received
Cruise vehicle speed value and actual vehicle speed that block sends, judge whether to need to carry out vehicle braking, if that is, actual vehicle speed is higher than to patrol
Boat vehicle speed value, then need braking, and braking instruction is sent into retarder, and retarder performs deceleration.
Engine control module receives the enabling signal and cruise vehicle speed value of constant speed continuation of the journey switch on vehicle instrument desk, starts
Whether machine control module judges actual vehicle speed less than cruise speed, if actual vehicle speed is less than cruise speed, engine control
Module control engine realizes cruise speed.
All signal transmissions pass through vehicle power CAN.Retarder uses existing retarder, retarder to be fixed on
On gearbox, the input shaft of retarder is fixedly connected with the output shaft of gearbox, and output shaft and the vehicular transmission shaft of retarder are consolidated
Fixed connection, retarder receives the control signal of retarder control module.
The course of work of the invention is, after constant-speed-cruise switch is opened, engine is connected to the startup letter of constant speed continuation of the journey switch
Number i.e. cruise instruction send cruise message to power bus on.Retarder can determine that the car of user's request after receiving cruise message
Speed.After vehicle enters cruise, at more flat road surface or upward slope normally travel, Engine ECU is by controlling distributive value for such as vehicle
Realize that constant speed of vehicle cruises, vehicle is in descending, if speed is beyond the cruise speed of setting, retarder can then drop by braking
Low speed realizes cruise to sets requirement.
The present invention is under realizing vehicle using the integrated demarcation of retarder constant speed shelves function and engine cruise function
Slope cruise, the braking realization that distributive value and retarder constant speed shelves when engine cruises are coordinated by vehicle bus will by driver
The speed asked, open cruise after no matter the highway of any road conditions, driver without go again control gas pedal, without under
Because speed is required and control braking of slowing down beyond cruise during slope, driving fatigue is alleviated, while reduce unnecessary speed becoming
Change, fuel can be saved.
