A steering control device is configured to control a steering device that changes a transmission ratio between an operation angle of an operation member and a steering angle of a steerable wheel. The steering control device includes: communication lines for transmitting vehicle speed information; and calculators communicably connected to each other and individually connected to the communication lines. Each calculator calculates the transmission ratio based on the vehicle speed information received via a corresponding one of the communication lines and determines whether the received vehicle speed information is valid. When at least one of the calculators determines that the vehicle speed information is not valid, each calculator changes control for calculating the transmission ratio from a vehicle-speed responsive control in which the transmission ratio is calculated based on the vehicle speed information to a specific control in which the transmission ratio is calculated not based on the vehicle speed information.

A steering control device controls a turning motor that generates a turning force for causing turning wheels of which power transmission to and from a steering wheel is cut off to turn. The steering control device includes a first processor configured to change a steering angle ratio which is a ratio of a turning angle of the turning wheels to a steering angle of the steering wheel according to a vehicle speed through control of the turning motor and a second processor configured to change a degree of change of the steering angle ratio with respect to change of the vehicle speed according to a steering state or a vehicle state.

A steering device includes a turning shaft, a turning motor, and a control device that controls the turning motor such that an angle capable of being converted into a turning angle of a turning wheel follows a target angle that is calculated depending on a steering state of a steering wheel. The control device executes a correction process of correcting the target angle. The control device corrects the target angle such that the degree of an increase in the target angle is slower as the target angle approaches a limit value of an angle region, when the target angle increases toward the limit value of the angle region in either of a vehicle stop state or an extremely low speed state.

A server receives a return request of a rental car including information on a usage end position of a car rental service desired by a user from a terminal of the user who has rented a rental car or the rental car. The server searches for a remote driving route of the rental car based on the information on the usage end position and information on a destination of the rental car for after the user finishes using the car rental service. The server compares the remote driving route with a communication area on a map. Then, the server transmits information indicating permission to drop off the rental car to the terminal of the user or the rental car when an entire route of the remote driving route is located inside the communication area.
