Embodiment Construction

[0051]Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar parameters or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0052] A start assist control method and system provided by the present invention, by adjusting the position of the clutch sensor, the clutch switch sends a clutch switch signal to the electronic control unit when the driver depresses the clutch pedal lightly, so that the electronic control unit (ECU) enters the control state in advance , Therefore, the given clutch switch signal time is longer, and the correct reaction can be made to the starting process in advance.

[0053] In order to better understand the technical solutions and tec...

Abstract

The invention discloses an auxiliary starting control method and system. The method comprises steps as follows: the position of a clutch switch is adjusted in advance, so that the clutch switch sends a clutch switch signal to an electronic control unit when a clutch pedal is in a calibrated position, namely, the calibrated position 5%-30% of the largest displacement of the clutch pedal. By comparison with a traditional calibrated position, namely, the position 90% of the largest displacement of the clutch pedal, a driver steps on the clutch pedal until the clutch pedal is moved by 5%-30%, a clutch switch circuit is connected with the signal, so that an ECU (electric control unit) starts a control state in advance and can respond to the starting process correctly in advance; when a vehicle is stopped and the electronic control unit receives the clutch switch signal, the vehicle is regarded as in a starting stage, a first increment is increased for a target idle speed, an engine is under idle speed control at an adjusted target idle speed, and the problem that a small-displacement engine is difficult to start is effectively solved.

Description

technical field [0001] The invention relates to the field of clutch control, in particular to a start assist control method and system. Background technique [0002] As energy saving and environmental protection are paid more and more attention, passenger car gasoline engines are developing towards supercharging and miniaturization. However, when the small-displacement engine is at low speed, the supercharger does not work at this time, and the output torque is relatively small, especially in the idling condition, which makes it more difficult for the vehicle to start. [0003] In addition, there are more and more trainee drivers. It is also very common that the accelerator and clutch do not cooperate well or even do not step on the accelerator when driving a manual transmission vehicle, causing the vehicle to stall when starting. [0004] In order to solve the above problems in the prior art, a torque control strategy of a linear clutch position sensor is usually used to i...
