Abstract

The invention relates to a longitudinal speed tracking control method of a self-adaptive driver type intelligent vehicle. The longitudinal speed tracking control method comprises the following steps that vehicle speed information is collected by a data collecting unit in real time; the information collected in the previous step is preprocessed by a data processing unit; a driver type is manually input to a logic operation unit, and the target vehicle speed of a system is automatically read; whether the vehicle needs to be accelerated or decelerated or not is judged; a corresponding acceleration control module or a corresponding deceleration control module is entered according to judgment results of the previous step; and calculation results of the previous step serve as output signals to be output to a corresponding line control system. According to the longitudinal speed tracking control method, highly acceptable longitudinal speed tracking control strategies of the intelligent vehicle are provided for drivers with different characteristics, vehicle driving safety and riding experience are improved, meanwhile, an acceleration and brake switching strategy in the design avoids frequent action of a longitudinal dynamic system at unnecessary time, safety of vehicle longitudinal control is improved, and energy consumption is lowered.

Description

technical field [0001] The invention relates to a longitudinal speed tracking control system and control method of an intelligent vehicle, in particular to an adaptive driver (passenger) type intelligent vehicle longitudinal speed tracking control system and control method. Background technique [0002] With the rapid development of smart car-related technologies, the degree of intelligence of vehicles is gradually increasing, and drivers will gradually be liberated from heavy driving tasks. Especially in longitudinal control, the existing cruise control and adaptive cruise systems have been applied on a large scale, which greatly reduces the driver's driving burden. However, the pursuit of more intelligent and humanized longitudinal speed control is still the development direction of the longitudinal speed control of intelligent vehicles. [0003] The longitudinal speed control of the smart car is the key core part of the smart car to achieve unmanned driving in the longit...
