Description
Technical field
Automotive power technical field is the utility model is related to, particularly a kind of vehicle top bar accessory system.
Background technology
At present, Car design has carried out more research to the brakes under automobile climbing state.But currently for
Automobile climbing form it is more single, and road conditions of the automobile in specific climbing are diversified, such as have the road of similar step
Condition, also there are relatively flat road conditions.
Using current brakes, the situation of top bar is needed out for vehicle, it usually needs first to a large throttle
Make vehicle climb steps, then brake the article or building avoided knocking on step again, first here in the presence of the place of a contradiction
The throttle given, which crosses conference, makes vehicle that there is very big power to rush to step, then very likely knocks the article on step or builds
Build；If the throttle given is too small, vehicle climbs not top bar again.Automobile is very more in the operating mode of actual use, climbs step or road
Serratd edge is also situation about run into, but vehicle does not do for these operating modes and optimized, and causes to overcome these situations to need to drive
The superb driving technology of person, this undoubtedly adds vehicle safety risk.
Utility model content
Goal of the invention of the present utility model is：For above-mentioned problem, there is provided a kind of vehicle top bar auxiliary
System.
The technical solution adopted in the utility model is such：A kind of vehicle top bar accessory system, specifically includes first
Ultrasonic sensor, the second ultrasonic sensor, entire car controller, motor and wheel, first ultrasonic sensor
It is arranged in the second ultrasonic sensor on the chassis of vehicle centre-line, first ultrasonic sensor is located at front vehicle wheel
The front of front end edge line, second ultrasonic sensor is located at the front of rear wheel front end edge line, described
First ultrasonic sensor and the second ultrasonic sensor are sequentially connected entire car controller, motor and wheel.This programme
Vehicle accessory system of appearing on the stage is corresponding construction for electric car.
Further, the entire car controller and motor are replaced by engine controller and engine respectively.We
The vehicle of case accessory system of appearing on the stage is corresponding construction for fuel vehicle, and the control unit and power unit of fuel vehicle are hair respectively
Motivation controller and engine.
Further, the distance of first ultrasonic sensor and front vehicle wheel front end edge line is N, described second
The distance of ultrasonic sensor and rear wheel front end edge line is N, and the span of the N is 5 ~ 12cm.
Further, the N takes 10cm.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：This programme increase ultrasound
Sensor carries out ranging, and cost is low；And by the automobile chassis that sonac measures and the distance on step ground, make to start
The moments of torsion of step needs is climbed in distribution automatically for machine controller or entire car controller, ensures disposably to climb up in step, and after climbing up
Torque output is 0, ensures the safety of driver and crew and vehicle.
Structure based on this programme, when automobile needs top bar, quick light stepping on accelerator pedal can trigger in auxiliary twice
Stepfunction, safe operation are simple.
Brief description of the drawings
Fig. 1 is the schematic diagram that the utility model will start top bar in vehicle front-wheel.
Fig. 2 is that the utility model is located on step in vehicle front-wheel, and vehicle rear wheel will start the schematic diagram of top bar.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
By taking electric car as an example, a kind of vehicle top bar accessory system, specifically include the first ultrasonic sensor 1, the second surpass
Sonic sensor 2, entire car controller, motor and wheel, the ultrasonic sensor of the first ultrasonic sensor 1 and second
2 are arranged on the chassis of vehicle centre-line, and first ultrasonic sensor 1 is located at front vehicle wheel front end edge line
Front, the first ultrasonic sensor 1 identifies that front vehicle wheel will be close to step by testing with the distance on ground, described the second to surpass
Sonic sensor 2 is located at the front of rear wheel front end edge line, the first ultrasonic sensor 2 by test with ground away from
From identifying that rear wheel will be close to step, the ultrasonic sensor 2 of the first ultrasonic sensor 1 and second is sequentially connected whole
Vehicle controller, motor and wheel.Entire car controller realizes the logic control of top bar by the control to motor.
By taking fuel vehicle as an example, in the structure based on electric car embodiment, the entire car controller and motor respectively by
Engine controller and engine replace.Engine controller realizes the logic control of vehicle top bar by the control to engine
System.
Step recognition principle：When speed is less than 5km/h, engine controller or entire car controller gather the first ultrasonic wave
The value of the ultrasonic sensor 2 of sensor 1 and second feedback, calculate the first ultrasonic sensor 1 and the distance H1 and second on ground
Ultrasonic sensor 2 and the distance H2 on ground, as shown in Figure 1.When H1 value reduces H due to step suddenly, H is the height of step
Degree, there have been Fig. 1 situation, vehicle front-wheel will start top bar, and high using the value H that H1 reduces suddenly as step
Degree.During front-wheel top bar, H1 can gradually increase, and H1 is held essentially constant after complete step on front-wheel.When on front-wheel
Quickly will occur trailing wheel after step close to crossing step；As shown in Fig. 2 during trailing wheel is close to step, H2 value meeting
The H because step diminishes suddenly, now think that trailing wheel will start top bar, H2 can gradually increase during trailing wheel top bar
Greatly, H2 value is held essentially constant after complete step on trailing wheel.
Top bar control logic：When recognizing front-wheel or trailing wheel will start top bar, driver only needs quick light
Twice, engine controller or entire car controller will adjust the size of output torque to stepping on accelerator pedal according to shoulder height,
When starting top bar, output torque can gradually increase, and 2/10 height has been climbed up until being measured by ultrasonic wave, has now been exported
Moment of torsion reaches maximum；Output torque will be constant within 2/10 to 7/10 time of shoulder height, the 7/ of climb steps height
Output torque progressively reduces after 10, and output torque is kept to 0 after step has been climbed.When vehicle does not detect step, start
Machine or entire car controller are according to the conventional normal response driver quickly operation of light stepping on accelerator pedal twice.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
