A computer-implemented method for braking control of a host vehicle includes detecting a panic brake operation based on a change of a braking pressure of a braking system of the host vehicle with respect to time. The method includes detecting a second vehicle driving behind the host vehicle and in the same lane as the host vehicle, and determining a time-to-collision value between the host vehicle and the second vehicle. Further, the method includes determining a deceleration rate of the host vehicle based on a driver braking pressure provided by operation of a brake pedal of the braking system. The method includes controlling the braking system based on the time-to-collision value and the deceleration rate.

A straddled vehicle includes a front wheel, a rear wheel, an engine which generates a driving force and rotates the rear wheel with the driving force, a front wheel brake and a rear wheel brake which lowers the rotation speed of at least the rear wheel, a first detector which acquires and outputs a pitch rate, a second detector which detects and outputs information concerning rotation of the front wheel, and an ECU including a front wheel lift determination circuit which monitors respective outputs from the first detector and the second detector to determine whether a front wheel lift exists based on at least one of the pitch rate and information concerning rotation of the front wheel. When the front wheel lift exists, the ECU controls the driving source or the braking device so that the driving force is lowered or the rotation speed of the rear wheel is lowered.

A method includes an initial trailer health assessment and real-time trailer health monitoring. The initial trailer health assessment includes autonomous pre-trip maneuvers of the autonomous vehicle during a first time period, and detecting a pre-trip vehicle health condition. A vehicle health score is calculated based on the pre-trip vehicle health condition. If the vehicle health score is at least a threshold value, real-time trailer health monitoring is performed during a trip of the autonomous vehicle during a second time period, by actively monitoring vehicle dynamics data and/or image data associated with the autonomous vehicle, to determine a fault condition of the autonomous vehicle. If the fault condition meets a first criteria, a control parameter and/or a travel plan of the autonomous vehicle is adjusted. If the fault condition meets a second criteria different from the first criteria, a signal is sent to cause the autonomous vehicle to cease movement.
