2results about How to "Increase drive torque" patented technology

A drive control device of an electric vehicle includes: brake devices (30a to 30d) provided respectively at left and right wheels of the vehicle; a front motor (4) and a rear motor (6) that drive and regeneratively brake the wheels of the vehicle; a vehicle motion control section (37) that calculates a brake additional demand amount corresponding to an additional amount of a yaw moment added to the vehicle, in accordance with a running state of the vehicle; a brake ECU (31) that controls the brake devices (30a to 30d) independently of each other in accordance with the brake additional demand amount to control a yaw moment of the vehicle; and a motor torque control section (39) that controls drive torque and regenerative braking torque of the front motor (4) and the rear motor (6), the motor torque control section (39) executing correction to increase the drive torque or decrease the regenerative braking torque in accordance with an increase in braking torque of the brake devices (30a to 30d) in accordance with the brake additional demand amount.

This utility model discloses a speed-adaptive variable pitch vertical axis hydroelectric power generation device for pipelines, including a generator, a transmission output shaft, a counterweight adjustment mechanism, and an impeller mechanism. The generator is coaxially connected to the transmission output shaft. The transmission output shaft is equipped with a counterweight adjustment mechanism and an impeller mechanism. When the transmission output shaft rotates, the counterweight adjustment mechanism generates a suitable centrifugal force to control the blades of the impeller mechanism to adaptively extend outward and retract inward, thereby automatically regulating the speed of the impeller mechanism. Therefore, by adopting this solution, the speed of the impeller mechanism can always be maintained within a preset range, thus effectively solving the problem that the speed of existing water turbines cannot be maintained within the rated speed range of the generator.
