Problems solved by technology

A short circuit fault means that the mechanical relay cannot return to the normally open state properly, which eventually leads to damage to the starter motor
An open circuit fault means that the mechanical relay is unable to close the metal contacts, so the starter motor cannot get power to energize and run
[0003] Furthermore, the current vehicle starting circuit has a single function, that is, it is only used to start the starter motor without other protection or safety mechanisms. In other words, the current vehicle starting circuit cannot avoid failures caused by human negligence

Embodiment Construction

[0042] In the following, the composition, working process and achieved effects of the electronic relay of the present invention will be described with reference to the accompanying drawings and corresponding preferred embodiments. However, the composition of the electronic relay, the electronic components and the flow of the method in each drawing are only used to illustrate the technical features of the present invention, but not to limit the present invention.

[0043] like figure 1 As shown, the vehicle starter circuit 10 is used to start the starter motor 30 and includes a battery 11 , a starter switch 13 , two front-end controllers 15 a, 15 b, two output switches 17 a, 17 b and an electromagnetic switch 19 . In this embodiment, the two output switches 17a, 17b are integrated circuits including P-type power transistors, but in fact the output switches 17a, 17b can also be a single transistor or a circuit composed of transistors, so the output switches 17a, 17b Not limited...

Abstract

A working method of a front controller of a vehicle starting circuit provided by the invention is configured to control an output switch of the vehicle starting circuit, and comprises the following steps: firstly, a battery voltage is measured; secondly, when the battery voltage is less than a false starting voltage value and an outage voltage value, the output switch is controller to allow the output switch to switch on, and the outage voltage value is less than the false starting voltage value and larger than zero; and when the battery voltage is larger than the false starting voltage value, the output switch is switched off.

Description

technical field [0001] The invention relates to a vehicle starting circuit, in particular to a front-end controller of a vehicle starting circuit and a working method thereof. Background technique [0002] The on-board starting circuit is used to start the on-board starter motor. At present, the on-board starting circuit uses mechanical relays. The metal contacts of mechanical relays are usually prone to metal contact failure after long-term use. The causes of failure include short circuit and open circuit. A short circuit fault means that the mechanical relay cannot return to the normally open state normally, which eventually leads to damage to the starter motor. An open circuit fault means that the mechanical relay is unable to close the metal contacts, so the starter motor cannot get power to energize and run. [0003] Furthermore, the current on-vehicle starting circuit has a single function, that is, it is only used to start the starter motor without other protection o...
