An operation management system configured to manage operations of registered mobilities in a limited specific area, including a computer configured to: generate a road surface map data such that a position in map data and road surface information are associated with each other, based on positional information and road surface information obtained from at least one of the registered mobilities on which a road surface condition detecting device is installed; compute a positon where a puddle is formed, based on i) one of water sprinkling information that is information on water sprinkling over a road surface by a sprinkler vehicle or weather information of the specific area and ii) the road surface map data; designate a designation mobility from among the registered mobilities and modify a target route of the designation mobility based on the puddle position; and send a command regarding the modified target route to the designation mobility.

Operation management system

A vehicle control device includes: a steering device, a steering control device, a surroundings monitoring device, and a controller. The controller is configured to execute: a route calculating process of calculating a target route, a trajectory calculating process of calculating a target trajectory of an own vehicle in one or more roads of the target route; a steering-angle calculating process of calculating a target steering angle; a behavior detecting process of detecting information on a behavior of the own vehicle; a rut determining process of determining presence or absence of a rut on the target trajectory based on a detection result obtained by the surroundings monitoring device and/or a detection result obtained in the behavior detecting process, a drivable or non-drivable determining process of determining whether the own vehicle is drivable over the rut, and a correcting process of correcting the target trajectory and/or the target route.

Vehicle control device including control based on determined ruts in the road

A hydraulic brake system for a vehicle, including: a wheel brake device configured to generate a braking force based on a pressure of a working fluid; a first brake system including a high-pressure source device including an accumulator and a first pump device that is driven intermittently such that a pressure of the working fluid in the accumulator is not lower than a set lower limit pressure and not higher than a set upper limit pressure; a second brake system including a second pump device; and a main power source that supplies electricity to the first and second brake systems, wherein the hydraulic brake system includes an auxiliary power source that supplies electricity to the first brake system when a failure occurs in the main power source, and wherein the first pump device is continuously driven when the failure occurs irrespective of the pressure in the accumulator.

Hydraulic brake system

A vehicle control system is configured to, when anti-skid control is started in a situation in which driving support control is being executed, execute a specific process for making a stop condition of the anti-skid control difficult to be satisfied as compared to when the driving support control is not being executed.

Vehicle control system

An override conciliating portion executes processing to conciliate an override request during an execution of automated driving control (i.e., override conciliation processing). In the override conciliation processing, it is determined whether or not there is the override request (step S). If the determination result of the step Sis positive, it is determined whether or not a second automated driving mode is selected as an operation mode (step S). If the determination result of the step Sis negative, acceptance processing of the override request is executed (step S). If the determination result of the step Sis positive, invalidation processing of the override request is executed (step S).
