Abstract
A remote parking control system and a fail-safe method thereof may include at least one controller and a remote parking control apparatus that performs braking control according to motor reverse torque control and transmission stage control, when a braking controller among the at least one controller fails, upon remote parking control.
Claims17
A remote parking control system, including:
- at least one controller;
- and
- a remote parking control apparatus configured to perform braking control according to motor reverse torque control and transmission stage control, when a braking controller among the at least one controller fails, upon remote parking control,
- wherein the remote parking control apparatus is configured to request a driving controller and a transmission controller among the at least one controller to control a target driving torque and a transmission stage, depending on whether it is possible to use a reverse torque,
- transmit the reverse torque to the driving controller and to request the transmission controller to maintain a current transmission stage, when it is possible to use the reverse torque, and
- request the transmission controller to change the current transmission stage without transmitting the reverse torque to the driving controller, when it is impossible to use the reverse torque.

A fail-safe method in remote parking control, the fail-safe method comprising:
- determining whether one of at least one controller and a remote parking control apparatus fails, upon the remote parking control;
- performing braking control according to motor reverse torque control and transmission stage control when a braking controller among the at least one controller fails;
- requesting a driving controller and a transmission controller among the at least one controller to control a target driving torque and a transmission stage, depending on whether it is possible to use a reverse torque;
- transmitting the reverse torque to the driving controller and to request the transmission controller to maintain a current transmission stage, when it is possible to use the reverse torque;
- and
- requesting the transmission controller to change the current transmission stage without transmitting the reverse torque to the driving controller, when it is impossible to use the reverse torque.
