Embodiment 1

[0024] see figure 1 , the parking control system integrating BSD and SDG functions of the present invention is composed of APA host, automatic parking sensor, blind spot monitoring sensor, flank protection sensor, corresponding function switch, status indicating LED, instrument display and sound prompt;

[0025] The APA host computer includes an automatic parking control unit, a blind spot monitoring control unit and a flank protection control unit; the automatic parking control unit is used to receive the signal from the automatic parking sensor and calculate and plan a reasonable parking path, which is displayed through the instrument and voice prompts to guide the driver to control the vehicle to park smoothly into the parking space; the blind spot monitoring control unit is used to receive the signal from the blind spot monitoring sensor and calculate the distance of the obstacle, and warn the driver to be careful when the BSD warning indicator light is turned on. Road; th...

Embodiment 2

[0030] see figure 1 , figure 2 , image 3 , the parking control system of the integrated BSD, SDG function of the present embodiment is different from Embodiment 1, and further: the main control circuit of the APA host adopts a 32-bit microprocessor of the Frescale:SPC56 series, and each function switch is passed through The switch acquisition circuit is connected to the microprocessor of the APA host, and the power supply forms a ground loop through the first resistor, the second resistor and the third resistor, and the connection node of the first resistor and the second resistor is grounded through a functional switch, and the second resistor and the second resistor are grounded. The connection node of the third resistor outputs the switch state to be connected to the APA host; the state indication LED corresponding to each switch is connected to the corresponding I / O port of the microprocessor.

Embodiment 3

[0032] see figure 1 , figure 2 , image 3 , Figure 4 The parking control system of this embodiment integrating BSD and SDG functions is different from Embodiment 1 or Embodiment 2 in that further: the switch state indicates that the LED output circuit adopts the collector output of the LED access transistor circuit, and the The control base of the transistor is controlled and connected to the microprocessor of the APA host, and the LED output circuit adopts a low effective output, and the light is on when the GPIO port is low output; when the GPIO port is high output, the light is off.

[0033] The present invention integrates the parking control system of BSD and SDG functions. The automatic parking sensor includes 4 UPASensors for the front protection, 4 UPA Sensors for the rear protection, and 4 APA Sensors for the side wings, which are connected to the APA host through the APA switch; the blind spot monitoring The sensors include APA Sensors on both sides of the front...

Abstract

The invention relates to a parking control system integrating BSD and SDG functions. The parking control system comprises an APA host, an automatic parking sensor, a blind spot monitoring sensor, anda flank protection sensor. An automatic parking control unit of the APA host is used for receiving a signal of the automatic parking sensor and calculating and planning a rational parking route; a blind spot monitoring and controlling unit is used for receiving a signal of the blind spot monitoring sensor and calculating a distance from an obstacle; and a flank protection control unit is used forreceiving a signal of the flank protection sensor and calculating a distance from a flank obstacle. An automatic parking control method integrating the BSD and SDG functions comprises the following steps: pressing an APA switch, switching an APA state conversion module from a Standy state to an Active state, looking for a parking position, according to detected information, such as a length and awidth of the parking position, judging whether the parking position meets the requirements by a parking position detecting module, and according to a current real-time position, planning a parking track by a vehicle track calculating module; reminding, by a parking guide module, a driver to press a brake and put into a R-gear; and controlling a steering wheel to be turned to a target angle by an EPS control module, and backing into a parking garage.

Description

technical field [0001] The invention relates to a parking control system, in particular to an automatic parking control system and method integrating BSD and SDG functions. Background technique [0002] As there are more and more cars on the road and the roads are becoming more and more congested, it is a great challenge for many drivers to park in a small parking space quickly, safely and accurately. Semi-autonomous parking technology (hereafter referred to as APA) can park cars in smaller spaces than most drivers can park themselves. At present, in the domestic market, there are many mass-produced models that realize the semi-automatic parking function. However, the automatic parking control system integrating BSD (Blind Spot Monitoring) and SDG (Side Guard) functions is still blank. Based on the increasingly mature and stable development of ultrasonic radar sensing technology, it is of great practical significance to develop a reliable and expandable automatic parking co...
