specific Embodiment 1

[0020] see figure 1 , an intelligent vehicle starting operation assistance system, suitable for models equipped with manual transmission, including vehicle controller VECU, engine controller EECU, instrumentation, transmission output shaft speed sensor, transmission intermediate shaft speed sensor, Clutch pedal microswitch, transmission neutral switch, transmission half-shift switch and accelerator pedal.

[0021] see figure 1 , the vehicle controller VECU is respectively connected with the engine controller and the instrument, that is, the vehicle controller VECU, the engine controller EECU, and the instrument communicate with each other through the CAN bus. The gearbox output shaft speed sensor is connected to the meter, and the specific gearbox output shaft speed sensor is connected to the meter by a hard wire. The gearbox intermediate shaft speed sensor, clutch pedal micro switch, gearbox neutral switch, gearbox half gear switch and accelerator pedal are all connected to...

Embodiment 2

[0024] An intelligent control method for a vehicle starting operation assisting system, comprising the following steps:

[0025] Step 1. The vehicle controller VECU first judges when the vehicle is in the starting state. When the following conditions are met, the vehicle controller VECU considers that the vehicle is in the starting state: the clutch pedal is depressed, the gearbox is not in neutral, the engine speed The drop exceeds the calibrated value A, the gearbox input shaft speed changes suddenly, the engine torque changes suddenly, and the vehicle speed is lower than the calibrated value B. Both the calibration value A and the calibration value B here are the calibration values ​​of the test, and both are obtained based on a large number of user tests.

[0026] Step 2. When the vehicle starts, the vehicle controller VECU monitors the clutch's instantaneous slipping energy, cumulative slipping energy, slipping time, starting speed and real-time gear information of the ge...

Abstract

The invention discloses an intelligent vehicle starting operation assistant system and a control method thereof. The system comprises a vehicle controller VECU, an engine controller EECU, an instrument, a transmission output shaft rotational speed sensor, a transmission intermediate shaft rotational speed sensor, a clutch pedal micro switch, a transmission neutral gear switch, a transmission half-gear switch and an accelerator pedal. The method comprises the following steps: 1, the vehicle controller VECU judges when the vehicle is in the starting state; 2, the VECU of the whole vehicle control monitors the instantaneous slip wear energy of the clutch in real time, accumulates the slip wear energy, the slip wear time, the starting speed and the real-time gear information of the transmission, estimates the wear percentage of the clutch plate, and simultaneously starts to record the information relate to the starting operation of all the vehicles; and 3, that the vehicle exits from the vehicle starting operation assistant system. The intelligent vehicle starting operation assistant system enables the driver to start the vehicle through more standardized operation, improves the probability of the successful start of the vehicle, and greatly prolongs the service life of the clutch plate.

Description

technical field [0001] The invention relates to a vehicle start-up operation assisting system, more specifically to an intelligent vehicle start-up operation assisting system and a control method thereof, belonging to the technical field of automobile and component manufacturing. Background technique [0002] On models equipped with manual gearboxes, the complete vehicle starting operation includes: 1. Depress the clutch pedal and engage the gearbox; 2. Release the foot brake; 3. Release the clutch pedal while depressing the accelerator until The engine flywheel is fully combined with the clutch friction plate (the output shaft of the engine reaches the same speed as the input shaft of the gearbox). However, the driver must have a time difference between the two actions of releasing the foot brake and stepping on the accelerator pedal. way to deal with it. [0003] At present, the "hill start assist system" is usually installed on the vehicle, so no matter whether the vehi...
