Aspects concern a method for controlling a braking of a vehicle. The method including detecting a braking situation, determining a classification of the braking situation, selecting a braking profile based on the determined classification, and applying a deceleration based on the selected braking profile to maintain a safety distance based on the selected braking profile.

A regenerative braking control method of a vehicle, may include a first operation of determining a driving risk of a road surface on the basis of a status of the road surface while driving; a second operation of determining whether an accelerator pedal is released while driving; a third operation of determining whether a brake pedal is operated while driving; and a fourth operation of performing no regenerative braking when the accelerator pedal is determined as being released, the driving risk of the road surface is determined as being high, and when the brake pedal is determined as not being operated.

A method for managing a vehicle brake system includes collecting sensor data from one or more sensors in or around the vehicle, calculating brake effectiveness values based on the sensor data, calibrating the brake effectiveness values based on environmental context data associated with the vehicle, accumulating the calibrated brake effectiveness values as a dataset, generating a prediction curve or formula based the dataset, and scheduling a maintenance alarm for the brake system based on the brake effectiveness values.

A road surface condition estimation device extracts a detection signal of a vibration power generation element during a ground contact section to detect a road surface condition. A threshold used for determination of the ground contact section is variable according to a traveling speed of a vehicle. As a result, even if a pulse level of an output voltage of the vibration power generation element changes according to the traveling speed of the vehicle, the threshold corresponding to the change can be set. The ground contact section is determined with the use of the above thresholds, thereby being capable of performing the determination with high accuracy. Therefore, the road surface condition can be detected with high accuracy based on the ground contact section determined with high accuracy.

A bicycle braking system includes a server, a portable device such as a smartphone, a display unit, a control unit, a power supply unit, a rotating electrical machine, and a bicycle. The portable device includes an image display unit, a braking condition transmitting unit, and a braking condition setting unit. The control unit regeneratively brakes the bicycle using the rotating electrical machine in accordance with the braking condition set by the braking condition setting unit. The braking system enables a non-user to set braking conditions for the bicycle and to perform braking based on the conditions set by the non-user.

A riving assistance apparatus includes a sound wave control unit acquiring information of a reflected wave from a distance measuring unit, the distance measuring unit transmitting a sound wave towards a travelling direction of a vehicle and receiving the reflected wave of the sound wave reflected from an object, an information acquisition unit acquiring temperature information in surroundings of the vehicle, and a determination unit determining that a road surface in the travelling direction of the vehicle is a frozen road surface by determining that the distance measuring unit receives the reflected wave including a signal strength equal to or greater than a predetermined value from a predetermined distance or more, based on the information of the reflected wave in a state where a temperature based on the temperature information is smaller than a predetermined temperature.

A sound measurement system intended to be installed on a motor vehicle, the system comprising: a microphone, an element for supporting the microphone, mechanical means for protecting the microphone against various projections (water, dust, etc.) from the environment of the vehicle, and mechanical means for protecting the microphone from airborne noise originating from the routing of the sound wave between the source and the measurement (cavity noise) and from the environment of the measuring system (turbulence around the measuring device), the various mechanical protection means being separate or combined. A motor vehicle may be provided with such a system.

A method for braking a vehicle, including checking whether a trigger criterion for braking the vehicle is present, and if the trigger criterion is satisfied, causing a conditioning braking pulse through brief pulsed braking such that passengers experience brief braking of the vehicle, and immediately thereafter initiating a braking phase in which the vehicle is braked in at least two partial braking regions by an actual ego deceleration that varies with respect to time, wherein each partial braking region is extended over a partial braking interval and merge into one another without the actual ego deceleration changing abruptly, and the actual ego deceleration in at least one of the partial braking regions is changed continuously over the respective partial braking interval such that a different actual jerk is obtained in each partial braking region, and wherein the actual jerk behaves degressively over at least some partial braking regions.

An example operation includes one or more of determining, by sensors on a transport, a slope of a road and a surface condition of the road and engaging one or more wheels of the transport, based on the slope, the surface condition, and a characteristic of the one or more wheels. Engaging includes braking to the one or more wheels at a different rate as the transport is moving on the road.

A brake system includes a piston configured to generate hydraulic pressure of brake fluid stored in a brake system, and an electronic control unit (ECU) configured to calculate hydraulic pressure to be generated in response to an amount of movement of the piston. The ECU estimates a current temperature of the brake fluid, calculates a maximum estimated hydraulic pressure of the piston based on the estimated current temperature, and determines a maximum hydraulic-pressure reference value for backward movement control of the piston based on the maximum estimated hydraulic pressure.
