The invention relates to a hydrogen fuel cell vehicle collision detection method and system and a vehicle. The method comprises the steps that the acceleration value and the hydrogen concentration value of the vehicle are detected in real time, the duration time when the acceleration value is larger than a set acceleration threshold value is recorded, and impact force generated when collision occurs is sensed; comparing the impact force with an impact force threshold value, if the impact force is greater than or equal to the impact force threshold value, determining that the vehicle has a fault, if the impact force is less than the impact force threshold value, comparing the acceleration value with a set acceleration threshold value, and if the acceleration value is greater than or equal to the set acceleration threshold value, determining that the vehicle has a fault; if yes, the fault level of the vehicle is determined based on the duration time, a set time threshold value, the hydrogen concentration value and a set concentration threshold value, and if the acceleration value is smaller than a set acceleration threshold value, the vehicle does not have faults. According to the invention, the accuracy of the collision detection result can be improved.
