Abstract

The embodiment of the invention discloses a device for diagnosing faults of relays of a start stop device. The device comprises a first switch, a second switch, a collecting module and a processing module. The first switch is used for controlling the start stop chain relay to be turned on and turned off; the second switch is used for controlling the transmission chain relay to be turned on and turned off; the processing module is used for controlling the on-off states of the first switch and the second switch; the collecting module is used for collecting the voltage of the corresponding input end and / or the corresponding output end of the start stop chain relay and / or the transmission chain relay; the processing module is further used for diagnosing the faults of the start stop chain relay or the transmission chain relay according to the collected voltage of the corresponding input end and / or the corresponding output end of the start stop chain relay and / or the transmission chain relay. The embodiment of the invention further discloses a method for diagnosing the faults of the relays of the start stop device and a start stop system. The method and device can diagnose the faults of the relays of the start stop device and facilitate repair of the start stop device.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a relay fault diagnosis device and method for a start-stop system and a start-stop device. Background technique [0002] In recent years, with the rise of oil prices and the increasing severity of global warming, improving the fuel economy of cars and reducing carbon dioxide (CO 2 ) Issues such as emissions are imminent. Start-stop device is one of the methods to solve these problems. The start-stop device can automatically turn off the engine when the car encounters a red light or traffic jam, and automatically start the engine when the driver releases the brake pedal or steps on the clutch, thereby effectively reducing the car's frequent parking or starting conditions. fuel consumption. [0003] For safety reasons, the start-stop device generally controls the starter through two relays (drive chain relay and starter chain relay). However, in the prior art, there is no fault diagn...
