Problems solved by technology
However, the existing technology does not consider whether the energy storage battery can fully meet the electric power requirements of the driving process during the overtaking process of the electric vehicle.
If the energy storage system of the electric vehicle cannot support the acceleration power requirements for overtaking, it will lead to overtaking failure and even traffic accidents

Embodiment Construction
[0020] The electric vehicle overtaking system includes a detection module. The detection module includes a set of detection sensors and sensor information processing units for detecting its own vehicle speed, overtaking target vehicle speed, overtaking target distance, position and speed that may interfere with the target during overtaking, and can be used for overtaking. The overtaking processing module calculates various achievable overtaking driving schemes and post-processing schemes for overtaking failures according to the data collected by the sensors and the configuration of the power steering of the vehicle; the battery management system, according to the monitoring of the battery system To evaluate whether the power required for the implementation of the various overtaking driving plans and post-processing plans calculated by the overtaking processing module can be met; the navigation system, if the relevant vehicle has a communicable navigation system, the navigation sy...

The invention discloses an electric vehicle overtaking system, which comprises an overtaking processing module and a detection system. The detection system outputs acquired signals to the overtaking processing module, and the overtaking processing module outputs audio signals of overtaking prompt schemes to a voice prompt unit for playing. The detection system comprises a camera unit and a radar unit, the camera unit is mounted in the front of a vehicle to acquire forward image information, the radar unit is mounted in the front of the vehicle to acquire forward vehicle distance and speed information, and a battery management system acquires parameter information of a vehicular power battery and transmits to the overtaking processing module. The overtaking schemes are selected according topower supporting states of power batteries of electric vehicles; by consideration of overtaking failure driving schemes and coordination of associated vehicular navigation systems, safety and reliability of an electric vehicle overtaking process are improved, and voice prompting for a driver in a whole process can be realized.
Description
Technical field [0001] The invention relates to the field of electric vehicles. Background technique [0002] As the economy develops and technology advances, more and more vehicles are driving on the road, and traffic accidents also increase. There are many reasons for traffic accidents, such as driving out of control, sudden puncture, fatigue driving of the driver, accelerator pedal as the brake, etc. One of the important scenes is unsuccessful overtaking. To avoid unsuccessful overtaking leading to traffic accidents. [0003] At present, there are similar electric vehicle overtaking warning control methods. The existing technology mainly considers the geometric conditions of overtaking. Patent application 201510863996.3 proposes an overtaking warning method, which takes into account the distance between vehicles, the length of the vehicle, the speed of the two vehicles, and the sections available for overtaking. Length, patent application 201610840273.6 considers the distance ...
