An emergency start system based on the failure of the clutch switch of the mt vehicle with peps

Abstract

The invention provides an emergency starting system during clutch opening and closing breakdown based on the vehicle type of an MT with a PEPS. The emergency starting system comprises a clutch openingand closing signal collecting module, a breakdown judging module, a power supply state detection module, a starting and stopping button signal detection module, a braking signal detection module, ananti-theft authentication module and a relay control module. The clutch opening and closing signal collecting module is used for collecting a bottom opening and closing signal and a top opening and closing signal of a clutch. The breakdown judging module is used for judging whether the clutch breaks down or not according to the collected bottom opening and closing signal and the collected top opening and closing signal. The power supply state detection module is used for detecting the current power supply state. The starting and stopping button signal detection module is used for detecting whether a starting and stopping button is pressed or not and recording the time interval t of pressing the button and loosening the button. The braking signal detection module is used for detecting whether a brake is trod or not. The anti-theft authentication module is used for detecting whether anti-theft authentication passes or not. The relay control module is used for controlling a relay to attract for closing according to the detected power supply state, a starting and stopping button signal, a braking signal and an anti-theft authentication signal. According to the emergency starting system, during clutch opening and closing breakdown, safe starting of an automobile is ensured, and the emergency starting system is more convenient and more practical.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a vehicle model with manual transmission and PEPS. Background technique [0002] The clutch switch signal is divided into the following two states, that is, the top switch clutch signal and the bottom switch clutch signal. The acquisition of this signal is generally completed by the engine ECU or EMS, and the collected clutch switch signal is sent to the network for PEPS. To judge whether the starting conditions are met, the clutch switch signal of some models is collected by the BCM and sent to the network. Generally speaking, during the starting process, it is judged whether the clutch is stepped on according to the signal of the clutch switch at the bottom, and then it is judged whether the starting condition is met, and then PEPS controls the starting relay to be pulled high. [0003] Under normal circumstances, when PEPS detects that the clutch is stepped on, the bottom switch signa...
