A vehicle longitudinal driving safety distance estimation method based on vehicle trust belongs to the technical field of vehicle active safety, and optimizes a traditional vehicle safety distance model by introducing a vehicle trust concept, the vehicle trust is directly reflected as the control of a driver on a vehicle in the vehicle driving process, and indirectly reflected as the behaviors such as the distance of the kept safe vehicle distance and whether safe overtaking can be achieved or not. According to the method, the problems that in the prior art, a calculation result is not accurate enough, it cannot be guaranteed that the safety distance meets the expectation of the driver in real time, and practicability is not high are solved, the definition of the vehicle trust is provided,that is, the vehicle performance exerted by the driver is improved, and the judgment accuracy of the driver for the safety vehicle distance is improved.
一种基于车辆信任度的车辆纵向行驶安全距离预估方法,属于汽车主动安全技术领域,通过引入车辆信任度概念,优化传统的车辆安全距离模型,车辆信任度的直接体现为驾驶人在驾驶车辆的过程中对车辆的操控,间接体现为保持的安全车距的远近以及能否安全超车等行为。本发明解决了现有技术中涉及计算结果不够准确,无法实时保证安全距离符合驾驶人预期、实用性不强的问题,提出了对车辆信任度的定义,即驾驶人所能发挥出的车辆性能的大小,提高了驾驶人对安全车距判断的准确性。
