Abstract

The invention discloses an automobile and pedestrian warning integration and attachment development device, which comprises a circuit board being a built-in circuit board of an existing automobile and equipped with a power management module, a CAN conversion module, a DA module, a power amplifier module and a microprocessor module; wherein a pedestrian warning sound processing unit is integrated on the microprocessor module. According to the two low-cost development schemes of the pedestrian warning device, a control chip, a power management module, a CAN conversion module, a DA module and a power amplifier module which are arranged on an existing automobile circuit board are fully utilized, so that on the basis of meeting the pedestrian warning function, the product development cost is greatly reduced, and the cost of the pedestrian warning device on an automobile is reduced.

Description

technical field [0001] The invention relates to the technical field of the pedestrian warning field of electric vehicles, in particular to a vehicle pedestrian warning integration and dependency development device. Background technique [0002] In the past two decades, my country's automobile industry has developed vigorously, but it has also brought serious environmental pollution problems. Therefore, new energy vehicles have been vigorously promoted under the national policy guidance and industrial support in recent years. Electric vehicles and gasoline-electric hybrid vehicles (usually in low-speed electric, high-speed hybrid mode). [0003] When driving at high speed, the exterior noise of pure electric vehicles is mainly contributed by road-tire noise and wind noise, while the exterior noise of hybrid vehicles is mainly contributed by engine noise, motor noise, road-tire noise and wind noise. The level is basically the same, but when starting and driving at low speeds, ...
