The invention relates to the technical field of high-voltage cable fault detection, and provides a low-sampling high-voltage cable fault positioning method based on head edge correction and waveform quality weighting. The method comprises the following steps: deploying low-power-consumption wave recording terminals at two ends or key nodes of a high-voltage cable joint so as to collect a timestamp sequence when a high-voltage cable fault occurs; calculating a first edge slope, a signal-to-noise ratio and oscillation symmetry triggered by the first edge; calculating a waveform quality correction coefficient of the first edge based on the slope of the first edge, the signal-to-noise ratio of the signal and the oscillation symmetry; based on the timestamp sequence, screening subsequent timestamps strongly associated with the first edge by taking the first edge timestamp as a reference to obtain an effective timestamp sequence; and taking the first edge as a positioning reference, performing fitting correction on the deviation of the first edge by using the effective timestamp sequence and combining the waveform quality correction coefficient of the first edge to obtain a corrected first edge time difference, and further obtaining a fault position through a double-end positioning method.

This invention provides a vehicle control device and a vehicle control method. The driving control device includes a correction unit that performs a first correction process on a desired value when the vehicle is traveling uphill, and a second correction process on the desired value when the vehicle is traveling downhill. The first correction process corrects the desired value to increase the driving speed compared to a situation where the first correction process is not performed. The second correction process corrects the desired value to decrease the driving speed compared to a situation where the second correction process is not performed. During the execution of the first correction process, if a driver assistance device requests emergency braking of the vehicle, the correction unit reduces the correction amount of the desired value in the first correction process compared to a situation where emergency braking is not requested.
