The invention discloses a self-adaptive cruise control method for simulating driver characteristics based on fuzzy control. According to the technical scheme, the self-adaptive cruise control method comprises the steps of S10, acquiring vehicle driving information in real time; S20, acquiring a safe distance value, a two-vehicle collision time value and a target vehicle speed value of a vehicle through calculation; S30, configuring a fuzzy rule table, storing a plurality of vehicle distance states and a plurality of vehicle speed states in the fuzzy rule table, and determining the probabilityvalues of the vehicle in the vehicle distance states and the vehicle speed states; S40, further storing a plurality of vehicle working condition states in the fuzzy rule table, and calculating the probability values of the vehicle in the vehicle working condition states; S50, calculating an expected acceleration value of the vehicle; and S60, after receiving an intelligent driving instruction of adriver, controlling the vehicle according to the expected acceleration value. According to the self-adaptive cruise control method, the acceleration value during intelligent driving can be subjectedto personification control, thus, the smoothness and stability of the intelligent vehicle during intelligent driving are improved, and the experience of the driver is improved.
