Vehicle wireless key detection system and vehicle

Abstract

The invention relates to a vehicle wireless key detection system and a vehicle. The system comprises a low-frequency emission antenna arranged on a vehicle to send a low-frequency wireless signal covering the whole vehicle and a vehicle key including a key-free system detection module, a key low-frequency receiving device, a key high-frequency emission device and a key controller, a vehicle high-frequency receiving module and a control module. The key-free system detection system module can detect whether the vehicle key is in a coverage range of the low-frequency emission antenna; the key controller is configured in a way that when the vehicle key is detected to be in the coverage range of the low-frequency emission antenna, the key low-frequency receiving device is started to receive thelow-frequency wireless signal, and the key high-frequency emission device is started to send a high-frequency wireless signal at least comprising an authorization signal, a function signal and a low-frequency wireless signal RSSI strength signal; the vehicle high-frequency receiving module and the control module are arranged on the vehicle; the vehicle high-frequency receiving module receives thehigh-frequency wireless signal; and the control module authorize the authorization signal and judges according to the low-frequency wireless signal RSSI strength signal.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle wireless key detection system and a vehicle equipped with the vehicle wireless key detection system. Background technique [0002] In modern vehicles, the application of electronic control technology is becoming more and more extensive. With the rapid innovation of contemporary electronic product technology, various electronic products have been applied to vehicles in large quantities, realizing a comprehensive change in vehicle electronic control technology. The application of these electronic control devices is of great significance to environmental protection, energy saving, improvement of operating safety and comprehensive performance of vehicles. In recent years, keyless start / entry technology, as a new technology, has begun to enter the domestic passenger car market and has been favored by consumers. In the next few years, there is an increasing trend of keyl...

Problems solved by technology

However, this will cause the manufacturing cost to remain high all the time, thus increasing the cost of the vehicle

[0004] In addition, if Figure 1 to Figure 3 As shown in , since the coverage area of ​​the antenna is elliptical, it is difficult to conform to the shape of the vehicle

So, if figure 2 and image 3 As shown, when performing interior key detection and exterior key detection based on these existing keyless start / entry technologies, it is only possible to reduce as much as possible figure 1 The adverse effects of the blind spot area B inside the car and the overflow area C outside the car shown in , which cannot be completely resolved

[0005] In addition, due to the above-mentioned reasons, the key detection mechanism of the current keyless start / entry technology is not very accurate, and there are situations such as missed judgments, delayed judgments, and misjudgments, which not only affect the user experience of consumers, but also may cause damage to the vehicle. The safe use of
