Abstract

The invention discloses a low-speed driving prompting device and method for an electric automobile. The system comprises a power supply module, a CAN module, a main control module, an LPF module and apower amplifier module. Wherein the main control module is respectively connected with the power supply module, the CAN module and the LPF module, the power supply module is connected with a power supply of an electric vehicle through an external interface, the CAN module is connected with a CAN bus of the electric vehicle through the external interface, and the power amplifier module is connected with the LPF module; the power supply module comprises a main power supply unit and an awakening unit; the invention has the advantage of solving the problem that the electric vehicle in the prior art lacks prompt sound during low-speed driving and easily causes traffic accidents.

Description

technical field [0001] The invention relates to the field of electricity, and more specifically relates to a low-speed driving prompting device and method for an electric vehicle. Background technique [0002] Intelligent control (intelligent controls) is an automatic control technology that can autonomously drive intelligent machines to achieve control goals without human intervention. The rapid development of information technology and computing technology and the development and mutual penetration of other related disciplines have also promoted the continuous deepening of control science and engineering research. The development of control systems to intelligent control systems has become a trend. [0003] When electric vehicles (pure electric vehicles, hybrid electric vehicles, fuel cell vehicles, etc.) start in pure electric mode or drive at low speeds, the average external noise is significantly lower than that of traditional internal combustion engine vehicles, making...
