Embodiment 1

[0031] Embodiment 1: a kind of automobile power distribution system,

[0032] Including the front motor: used to drive the front wheels of the car to rotate, the front motor has a fixed reduction ratio of 1: a 1 the front derailleur;

[0033] Rear motor: used to drive the rear wheels of the car, the rear motor has a fixed reduction ratio of 1: a 2 rear derailleur; a 1 >a 2 ;

[0034] Power module: used to supply power to the front and rear motors;

[0035] Control module: control the output of the power supply module according to the vehicle speed V and acceleration to change the power P1 of the front motor and the power P2 of the rear motor;

[0036] 0) When the car starts, 0≤V≤10km / h, both P1 and P2 are at the rated power;

[0037] 1) When 10<V≤30km / h, and V is at a constant speed,

[0038] P1=V*a 1 *a 2 *T 1max *1.745*10 -3 / [πd(a 1 +a 2 )],

[0039] P2=0;

Abstract

The invention provides an automobile power distribution system and an automobile using the automobile power distribution system. The automobile power distribution system comprises a front motor, a back motor, a power source module and a control module. The front motor is used for driving front wheels of the automobile to rotate and the front motor is provided with a front transmission whose fixed deceleration ratio is 1: a1; the back motor is used for driving back wheels of the automobile to rotate and the back motor is provided with a back transmission whose fixed deceleration ratio is 1: a2; a1 is bigger than a2; the power source module is used to supply power to the front motor and the back motor; and the control module is used for controlling the output of the power source module according to the automobile speed V and the accelerated speed so as to change the power P1 of the front motor and the power P2 of the back motor. According to the automobile power distribution system, the motors with the fixed deceleration ratio is adopted; shifting is not needed; rotating speeds of the motors can be maintained in a certain range; and power efficiency of the power source can be guaranteed under the working condition benefiting for the operations of the motors.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile power distribution system and an automobile using the automobile power distribution system. Background technique [0002] In order to adapt to the frequently changing driving conditions and make the engine work under favorable conditions (higher power and lower fuel consumption), that is, the efficiency of the engine can be high only within a certain speed range. transmission. [0003] A general car has multiple gears, and each gear has a different transmission ratio, which is equivalent to the meshing of the small gear and the large gear to produce different speeds. The rotation speed is lower than the engine speed. According to the formula P=FV, greater driving force can be obtained. At high speed, use a high transmission ratio (4th gear and above), and the rotation speed of the large shaft is higher than the engine speed. Reduce traction to obtain higher speed, and cu...
