Abstract

The invention discloses a vehicle speed and mileage signal collection and output system. The vehicle speed and mileage signal collection and output system comprises a ring gear, a wheel speed sensor,an ABS control module, a meter and a tire radius writing device. The ring gear and the wheel speed sensor are fixed to a wheel hub bottom plate through a clearance fit. The wheel speed sensor and theABS control module are connected by a hard wire, the tire radius writing device and the ABS control module are connected by a CAN line, and the ABS control module and the meter are connected by a CANline. The vehicle speed and mileage signal collection and output system is high in versatility, can reduce the procurement cost and management cost generated by a vehicle speed output system in the whole vehicle production process, improves the utilization of the ABS system function, and improves the vehicle speed and mileage accuracy.

Description

Technical field: [0001] The invention belongs to the technical field of vehicle internal signal control design, in particular to a commercial vehicle speed and mileage output system, and also relates to a signal output method of the system. Background technique: [0002] The accuracy of vehicle speed and mileage is of self-evident importance to driving safety. With the increasing integration of modern automotive electronics and networking, the application range of vehicle speed signals is also becoming wider and wider. For light trucks, the vehicle speed and mileage signals are mainly collected by the odometer sensor to match the speed signal of the rear axle speed ratio, and then output to the instrument / EMS / EPS for vehicle speed conversion. The disadvantages of this technical solution are: [0003] 1. Systems such as instruments, EMS, and gearboxes need to be developed in combination with odometer sensors, resulting in many system parts and high management costs. [000...
