In a brake device for a saddle-type vehicle, including hydraulic front and rear wheel brakes and a first control unit that controls operations of the front wheel brake and the rear wheel brake, a second control unit includes a collision possibility determining section that determines a possibility of collision of an own vehicle with an obstacle ahead, the first control unit has an automatic brake controller that performs automatic brake control to automatically increase braking forces of the front wheel brake and the rear wheel brake, and in case where the collision possibility determining section determines that there is the possibility of collision, the automatic brake controller pressurizes the rear wheel brake to brake a rear wheel, and simultaneously pressurizes the front wheel brake up to a predetermined pressure at which a vehicle body posture is not changed by braking of a front wheel.

Systems and methods use cameras to provide autonomous navigation features. In one implementation, a method for navigating a user vehicle may include acquiring, using at least one image capture device, a plurality of images of an area in a vicinity of the user vehicle; determining from the plurality of images a first lane constraint on a first side of the user vehicle and a second lane constraint on a second side of the user vehicle opposite to the first side of the user vehicle; enabling the user vehicle to pass a target vehicle if the target vehicle is determined to be in a lane different from the lane in which the user vehicle is traveling; and causing the user vehicle to abort the pass before completion of the pass, if the target vehicle is determined to be entering the lane in which the user vehicle is traveling.

Upon detecting a current balise, an onboard system of a train calculates a speed curve based on measured traveling speed at a timing of the detection and sets a minimum required time period for traveling to each of a next balise and a balise subsequent to the next balise. Upon detecting the next balise, the onboard system compares a traveling time period from the timing of detecting the current balise to the timing of detecting the next balise with the set minimum required time period. The onboard system activates an emergency brake when the elapsed time period is shorter than the minimum required time period to stop the train.

A lane departure prevention system includes a controller configured to control a braking force of vehicle wheels such that a lane departure prevention yaw moment is applied to a vehicle. The controller determines whether there is a likelihood that the vehicle enters a spinning state based on at least one of a difference between an actual yaw rate and a normative yaw rate of the vehicle calculated based on a steering angle, a vehicle speed, and the lane departure prevention yaw moment, and a degree of braking slip of a turning inside wheel when the lane departure prevention yaw moment is a yaw moment for preventing departure of the vehicle from a lane to a turning outside, and applies a spin prevention yaw moment to the vehicle when it is determined that there is a likelihood that the vehicle will enter the spinning state.

A control device for a first motorized pressure build-up device of a braking system of a vehicle. The control device is designed to output at least one first piece of information to an activation device of a second motorized pressure build-up device of the braking system by, under consideration of the respective first piece of information, a first motor activatable in such a way that a pressure prevailing in at least one partial volume of the braking system is varied in accordance with a pressure change signal, which is interpretable as the respective first piece of information for the activation device using a second pressure sensor unit of the second motorized pressure build-up device.

A method of controlling braking of a vehicle is provided to minimize heat generation in a brake system at a time of braking the vehicle while securing an appropriate braking force. The method includes determining whether an inclination condition for a road satisfies a preset condition, and when the inclination condition for the road satisfies the preset condition, performing cyclic brake control of alternately braking wheels of two or more different axles of the vehicle.

Vehicle systems include features for performing remote park assist (RePA) operations. One system include a feature where a user provides a continuous input via a touchscreen on a mobile device. The mobile device transmits a message and a vehicle autonomously traverses a calculated parking path while the message is being received by the vehicle. Another system include a feature where the vehicle autonomously move to a parking space based on data received from the mobile device. The mobile device receives user inputs on a display showing representations of the vehicle and its surrounding areas to generate the data. Another system include a feature where the mobile device determines whether the user is a first time user of a RePA application. The mobile device operates in a certain training mode based on the determination.
