Vehicle start control method and device

Abstract

The invention relates to a vehicle start control method and device. The method comprises the steps that vehicle starting information is acquired; and when the vehicle starting information indicates that a vehicle is started by a mobile Bluetooth key, a Bluetooth key starting signal is continuously sent out at a preset frequency, and the Bluetooth key starting signal is used for providing starting information required to be acquired from the mobile Bluetooth key when the vehicle is started, so that the vehicle can be started under the condition that the connection between the mobile Bluetooth key and the vehicle is disconnected. Therefore, on one hand, under the condition that the mobile Bluetooth key is disconnected from the vehicle, normal running and starting of the vehicle can be guaranteed, and the condition that the vehicle cannot be started on the half way due to power failure, fault or loss of the mobile Bluetooth key is avoided; on the other hand, the connection between the mobile Bluetooth key and the vehicle can be greatly saved, and the time for starting the vehicle by using the mobile Bluetooth key is saved, so that the vehicle can be started more conveniently.

Description

technical field [0001] The present disclosure relates to the field of vehicles, and in particular, to a vehicle startup control method and device. Background technique [0002] With the advent of the Internet era, smartphones or other smart wearable devices are becoming more and more common in life. In addition, the development of car-sharing or other rental car business has made more and more demands for remote key handover. Therefore, the use of mobile devices based on Bluetooth connectivity as a vehicle's starter key is increasingly being used. This Bluetooth-based electronic key (hereinafter referred to as Bluetooth key) can replace traditional mechanical keys or remote control keys in certain specific scenarios. Use the low-power Bluetooth module on the smartphone or other smart mobile devices to communicate with the low-power Bluetooth module on the vehicle, use the smart mobile device as the key of the vehicle, and use the smart mobile device to realize functions suc...

Problems solved by technology

[0003] However, the current bluetooth key design schemes all use the bluetooth key as a key, which is a one-time operation. keys, such as shared cars)

This solution will lead to the fact that once the smart device is out of power, malfunctions, etc., and the vehicle can no longer be used as a Bluetooth key to start the vehicle, the vehicle cannot be started again

In another solution, the Bluetooth key needs to be connected to the vehicle at all times. If the connection between the Bluetooth key and the vehicle is accidentally interrupted while the vehicle is running, for example, when the Bluetooth of the mobile smart device is connected to other devices, it may even affect the To the normal driving of the vehicle, this seriously affects the safety of the vehicle
