Vehicle travel control system

摘要

A vehicle travel control system includes a first unit configured to calculate a target longitudinal acceleration/deceleration control command of the own vehicle based on a distance or a relative speed between the own vehicle and a forward obstacle, traveling route information from a vehicle navigation system or a Global Positioning System, and input information such as a vehicle speed set by a driver; a second unit configured to calculate a target longitudinal acceleration/deceleration control command according to a lateral jerk that acts on the own vehicle; and an arbitration unit configured to perform, based on the target longitudinal acceleration/deceleration control command calculated by the second unit, arbitration of the target longitudinal acceleration/deceleration control command calculated by the first unit, wherein output from the arbitration unit is set as a command to control the target longitudinal acceleration/deceleration control command of the own vehicle.

1. A vehicle travel control system comprising:
a first unit configured to calculate a target longitudinal acceleration/deceleration control command of an own vehicle based on input information; a second unit configured to calculate a target longitudinal acceleration/deceleration control command according to a lateral jerk which acts on the own vehicle; and an arbitration unit configured to perform, based on the target longitudinal acceleration/deceleration control command calculated by the second unit, arbitration of the target longitudinal acceleration/deceleration control command calculated by the first unit, wherein
output from the arbitration unit is set as a command to control the target longitudinal acceleration/deceleration control command of the own vehicle,the arbitration unit calculates an acceleration period, and a deceleration period, and a steady period based on a target longitudinal acceleration/deceleration control command calculated by the second unit, andthe arbitration unit performs arbitration according to the calculated period,arbitration is to assign different values to at least the acceleration command, andduring the steady period the acceleration command is given a value of 0.
