Multi-sensor automobile racing state information acquisition system

Abstract

The invention discloses a multi-sensor automobile racing state information acquisition system. The objective of the invention is to solve the problems of functional simplicity, difficult data acquisition and poor data sharing of an automobile racing data acquisition system. The multi-sensor automobile racing state information acquisition system includes a Freescale single-chip microcomputer, a wheel speed sensor, a GPS, an engine ECU, a data acquisition device, a battery and a voltage-regulator chip; the battery and the voltage-regulator chip are connected with the Freescale single-chip microcomputer sequentially; the wheel speed sensor, an acceleration sensor, a rotation angle sensor, a suspension displacement sensor and the GPS are connected with the 5V ends of the Freescale single-chip microcomputer and the voltage-regulator chip; the engine ECU and the data acquisition device are connected with the 12V end of the battery; the signal line of the wheel speed sensor is connected with the pulse counting port of the Freescale single-chip microcomputer; the signal line of the rotation angle sensor and the signal line of the suspension displacement sensor are connected with the AD ports of the Freescale single-chip microcomputer; and the GPS is connected with the UART_TXD serial port and UART_RXD serial port of the Freescale single-chip microcomputer.

Description

technical field [0001] The invention relates to an information collection device in the technical field of automobile electronics, more precisely, the invention relates to a multi-sensor-based racing car state information collection system. Background technique [0002] With the rapid development of electronic technology and communication technology, more and more electronic auxiliary equipment will be added to the car to test and monitor the various performances of the car. In the vehicle manufacturing industry, the adjustment and analysis of vehicles plays a very important role in product development. After a prototype vehicle is designed and produced, it is necessary to collect data on the power system, chassis suspension system, etc., and perform adjustments. Traditionally, , this process is debugged according to the subjective feeling of the test driver, but this method has too many subjective factors to form exact data. [0003] In the field of Formula Student Automob...
