Abstract: A parking assist system which, after a vehicle has passed the side of a parking area formed between parked vehicles, assists parking of the vehicle from a stopped position of the vehicle to the parking area, the parking assist system comprising: a distance sensor that emits radio waves or ultrasonic waves and detects the distance to the parked vehicles on the basis of the reflected waves; parking area detecting apparatus that measures, when the vehicle passes the parked vehicles and the side of the parking area, the distance to the parked vehicles with the distance sensor and detects, after the vehicle has passed the side of the parking area, the parking area on the basis of the measurement result; parking target position calculating apparatus that calculates a parking target position of the vehicle on the basis of the parking area that has been detected by the parking area detecting apparatus; and vehicle trajectory calculating apparatus that calculates, on the basis of the parking target position of the veh

Abstract: To provide a parking assist system that can easily perform parking assistance even when a parking area is narrow and small.

Abstract: The invention concerns a process for evaluating the signal of an environment sensor of a motor vehicle, wherein from the signal lag time an offset of this signal is determined as well as an incline of the roadway, in that the signal is subject to a first filtering with a first time constant, in order to determine the incline of the roadway, and in that the signal is subject to a further filtering with a second time constant, in order to determine a possible offset of the signal, wherein, as the input of the filter for determining the incline of the roadway, a measurement signal adjusted by the output of the second filter is used.
