Problems solved by technology

[0003] Rapid acceleration and deceleration will affect the increase in fuel consumption of the car, and will also wear parts such as tires, engines, and braking systems, reducing service life and safety
Most of the existing research is on the acceleration controller, which is to adjust the speed and gear matching or optimize the ignition device to improve the combustion efficiency during acceleration to achieve the purpose of saving energy, without considering the fuel consumption caused by the safe state and wrong driving behavior

Abstract

The invention belongs to the field of automobile energy-saving methods, and discloses a driving active intervention system and method based on acceleration change rate optimization. By obtaining the front vehicle distance and the current vehicle speed, the optimal acceleration variable quantity which is uniformly changed when the current vehicle accelerates and decelerates suddenly under the safety condition is calculated, the accelerator or braking active intervention vehicle acceleration is assisted, the accelerator and pedal opening degree is reasonably adjusted, and active intervention ondriving operation is achieved. According to the method and the system, the purpose of reducing energy consumption can be achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile energy saving, and in particular relates to an active driving intervention system and method based on acceleration rate optimization. Background technique [0002] Studies have shown that under good vehicle and road conditions, the driver's driving behavior will affect fuel consumption, and improper driving behavior is a very important factor leading to high fuel consumption; it is mainly reflected in the following two situations: First, traffic congestion When the car cannot keep a safe distance, emergency deceleration is used in emergency situations; second, in ordinary traffic conditions, the driving behavior of acceleration is mostly rapid acceleration, and rapid acceleration and deceleration is an important factor that makes the fuel consumption of the car high. [0003] Rapid acceleration and deceleration will affect the increase in fuel consumption of the car, and will also wear parts su...
