Problems solved by technology
[0003] However, when a general car is in use, the inductive antennas inside and outside the car are in the state of the inductive key chip, which results in a large requirement for the battery capacity of the low-voltage battery
For internal combustion engine vehicles, the large battery capacity means that the volume and weight of the battery need to be increased, which is not conducive to the miniaturization and light weight of the vehicle

Embodiment Construction
[0044] In the present invention, the vehicle body control module is used to detect the door of the driving position, and when the door is detected to be opened, the first switch is closed to turn on the power supply of the low-voltage battery to the keyless start module, and then the keyless start module performs the first step of the key chip. The secondary verification reduces the power consumption of the low-voltage battery due to the non-stop detection of the induction antenna in the car after the car is locked.
[0045]In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0046] The keyless start system 1 provided by the embodiment of the present invention is used in an automobile provided with a first electrical appliance 16, a second electrical appliance 18 and a third electrical appliance...

The invention provides a starting system without keys. The starting system comprises a low-voltage storage battery, a car body control module, a key-free starting module and a first switch, wherein the car body control module is electrically controlled with the low-voltage storage battery; the key-free starting module is used for starting an engine and controlling a steering wheel to unlock; and the first switch is controlled by the car body control module and used for conducting the low-voltage storage battery to supply power to the car body control module when the condition that the door at the driving position is opened is detected by the car body control module. The invention further provides a starting method without the keys. With the adoption of the starting system and the starting method without the keys, the energy consumption of the low-voltage storage battery after the car is locked is reduced.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to a keyless starting system and a starting method. Background technique [0002] In the existing car design process, in order to realize remote control to open and close the door, a low-frequency antenna is generally installed on the door handle, and a card with a chip is used as the user's key. The user carries the chip within a certain distance from the car body. The door can be opened / closed remotely through the card in the hand. In addition, in order to prevent theft and prevent the use of the vehicle after entering the vehicle by other illegal means, the user must perform a chip verification after entering the vehicle before starting the engine. Correspondingly, the induction antenna is also installed in the car, that is, two verifications inside and outside the car are required. This way of entering the car is called Remote Keyless Entry (RKE). [0003] However, when a general c...
