Contents of the invention

The utility model provides an auxiliary device for starting a car in order to overcome the disadvantage that the manual transmission vehicle is easy to turn off when starting in the prior art.

In order to achieve the above object, the utility model adopts the following technical solutions:

A kind of automobile starting assisting device, described automobile comprises automobile chassis, clutch, engine control system and steering column; Described automobile starting assisting device comprises the displacement sensor that is arranged on the automobile clutch, and described displacement sensor is connected with engine control system .

The utility model is to install a displacement sensor on the clutch of the automobile, combined with the corresponding engine control strategy, to automatically compensate the power (engine speed, engine torque output) for the starting stage of the manual transmission automobile, and can effectively avoid the phenomenon of starting and stalling of the manual transmission automobile .

The displacement sensor is combined with the clutch, and the actual clutch engagement state and engagement process are fed back to the engine control system by sending a voltage or pulse width modulation signal.

When the car starts, the control process of the car engine control system is as follows:

The automobile engine control system receives the signal of the displacement sensor, calculates the position state of the clutch and the rate of change when the driver releases the clutch pedal; according to the situation of the clutch pedal, the automobile engine control system increases the engine speed and engine torque output, and combines the engine torque reserve , Complete the power output when the vehicle starts in advance, the driver does not need to step on the accelerator pedal, simplifies the operation steps, and effectively avoids the engine flameout phenomenon that occurs due to unskilled operation and insufficient power when starting.

Therefore, the utility model has the advantages that the driver can easily control the clutch and start without controlling the accelerator pedal, effectively reducing the probability of stalling at start; easy to implement, low in cost; short in development cycle; and strong in versatility.

Preferably, an acceleration sensor is also included, and the acceleration sensor is connected with the engine control system. The acceleration sensor is used to measure the slope of the road, and transmit the slope data to the engine control system, so that the power compensation when the car starts can take the slope data of the car into consideration, and make corresponding adjustments according to different slope conditions. Avoid the occurrence of engine flameout due to lack of power when starting.

Preferably, the acceleration sensor is arranged on the chassis of the vehicle.

Preferably, an angle sensor is also included, and the angle sensor is connected with the engine control system.

The angle sensor is used to measure the angle of the steering wheel, and transmit the angle data to the engine control system, so that the power compensation when the car starts can take the angle data of the steering wheel into consideration, so as to further avoid engine stalling due to insufficient power when starting occurrence of the situation.

Preferably, the angle sensor is located on the steering column.

Preferably, there are three displacement sensors. The setting of multiple displacement sensors can effectively avoid false detection.

Therefore, the utility model has the following beneficial effects: (1) Automatically compensates the power (engine speed, engine torque output) for the starting stage of the manual transmission vehicle, which can effectively avoid the phenomenon of the manual transmission vehicle starting and stalling; (2) It can make the driving The driver can easily control the clutch and start without controlling the accelerator pedal, effectively reducing the probability of stalling at start; (3) easy to implement and low cost; (4) short development cycle; (5) strong versatility.
