In a hydraulic brake system, when a main power supply is in an abnormal condition in which it cannot supply electric power to a pump motor, etc., the pump motor is operated with electric power supplied from an auxiliary power supply, irrespective of the presence of a braking request. Thus, when the main power supply is in the abnormal condition, the number of times inrush current flows is reduced. As a result, the voltage of the auxiliary power supply is less likely to be lower than an operation minimum voltage, and the hydraulic brake system is less likely to be unable to be operated.

A number of variations may include a method including pre-charging at least a portion of a vehicle brake system.

A number of variations are discloses including a system and method including using differential braking to reduce steering effort during loss of assist.

A smart communications hub can enable management of driverless and/or autonomous vehicles. Separating current wireless data from driverless vehicle sensor data can allow for quicker resolutions involving driverless vehicles. The smart communications hub can communicate to other groups such as driverless vehicle providers, service providers, vehicle management, law enforcement, etc. The smart communications hub can also process request from both mobile applications and micro-service applications.

A controller for a motorcycle includes a mode change section that changes a mode to a first mode in a state where a temperature of a rear-wheel friction brake mechanism is lower than a first prescribed temperature and to a second mode in a state where the temperature of the rear-wheel friction brake mechanism is higher than the first prescribed temperature during automatic deceleration in the automatic cruise operation. In the case where the braking forces generated on the rear wheel in the first mode and the second mode are compared under a condition that the same deceleration is generated in the motorcycle by the automatic deceleration, in a state where the deceleration is at least less than a first reference amount, the braking force generated on the rear wheel in the second mode is smaller than the braking force generated on the rear wheel in the first mode.
