For the manual-gear vehicle, the control chip judges whether the time that at least one path of starting key signals are kept pressed down reaches a fourth preset time, and at least one path of clutch signals are kept effective in the preset time. The fourth preset time is preferably 10 seconds.
And S33, when the judgment result is yes, the anti-theft authentication is requested for the automatic gear vehicle and the manual gear vehicle. The anti-theft authentication includes but is not limited to one-key starting system and smart key anti-theft authentication, one-key starting system and electronic steering column lock anti-theft authentication, one-key starting system and engine control system anti-theft authentication.
S34: no matter the vehicle is an automatic gear vehicle or a manual gear vehicle, when the anti-theft authentication is passed, the control chip sends a control instruction to the driving chip to control the output of the starting relay. In this embodiment, the driving chips include a high side driving chip for driving a high side of the starter relay and a low side driving chip for driving a low side of the starter relay. When the anti-theft authentication passes, the control chip sends a first control instruction to the high-side driving chip to control the high-end output of the starting relay, and the high-side driving chip sends a second control instruction to the low-side driving chip to control the low-end output of the starting relay.
And S35, detecting whether the output of the starting relay has a fault by the high-side driving chip and the low-side driving chip. The high-side driving chip and the low-side driving chip can judge whether the output has a fault or not through voltage detection/current detection. Faults that exist in the output of the start relay include short circuit to power, short circuit to ground, open circuit. And when the output is detected to have a fault, the step S36 is carried out, and alarm information is sent out and used for reminding the start of the relay to output the fault. The alarm information can be any one or combination of sound information, light information and vibration information. Further, after detecting the output fault, controlling the starting relay to stop the output. When output normality is detected, step S37 is performed: the starting relay switch is closed, the starter operates and drives the engine to start, and the vehicle starts.
In other embodiments, step S37 may be directly performed after step S34 without performing step S35.
For the starting method of the above embodiment, further comprising the steps of:
the control chip judges whether the acquired input of the start key signal has a fault, and when the acquired input of the start key signal has the fault, the control chip sends alarm information which is used for prompting a user to start the key input fault. The alarm information can be any one or combination of sound information, light information and vibration information.
Preferably, for the starting method of the above embodiment, after the control chip sends a control instruction to the driving chip to control the output of the starting relay, the control chip receives an input signal fed back by the starting relay, determines whether the input signal is consistent with the control instruction, and sends an alarm message when the input signal is inconsistent with the control instruction, where the alarm message is used to remind the control link of a fault.
This application triggers redundant detection and fault detection (two way start button signal and fault detection) through setting up, start condition redundant detection (two way brake signal input and two way gear signal detection, or two way separation and reunion signal detection), start output redundant control and fault detection (the high low end of start relay is controlled by different driver chip, and carry out fault detection), direct start is provided for the vehicle start, indirect start, three kinds of starting schemes of emergency start, can effectively avoid the vehicle mistake to start, and make the user can effectively start the vehicle under specific vehicle condition, satisfy the demand that user's intelligence started the vehicle in the at utmost.
It should be noted that the embodiments of the present invention have been described in a preferred embodiment and not limited to the embodiments, and those skilled in the art may modify and modify the above-disclosed embodiments to equivalent embodiments without departing from the scope of the present invention.
