Embodiment Construction

[0057]The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0058] The present invention is a pure electric vehicle mileage estimation device based on remote data transmission, such as figure 1 As shown, it includes a car navigator 1, a control unit module 2, a GPRS communication (wireless communication) module 3, a SOC (State Of Charge) calculation module 4, and an information center 5;

[0059] Car navigator 1 carries out GPS positioning to vehicle, obtains the position information of vehicle, and driver inputs destination into car navigator 1, and car navigator 1 sets driving route;

[0060] The control unit module 2 stores vehicle information, including vehicle model, vehicle parameters (total mass, length / width / height, maximum speed, acceleration performance, gradeability), motor parameters (rated voltage, rated power, maximum power, rated torque, maximum Torque, rated speed, maximum speed), the control u...

Abstract

The invention discloses a device for estimating the mileage of a pure electric vehicle based on remote data transmission, comprising a vehicle-mounted navigator, a control unit module, a GPRS communication module, an SOC calculation module, and an information center; For the location information of the vehicle, the driver inputs the destination into the car navigator, and the car navigator sets the driving route; the control unit module stores the vehicle information, including the vehicle model, vehicle parameters, and motor parameters, and the control unit module sets the driving route for the car navigator. The route is divided into several road sections, and a signal to extract the reference kinematics segment is sent to the information center through the GPRS communication module. After the control unit module receives the reference kinematics segment, it calculates the power consumption ΔC of the road section and outputs it to SOC calculation module, the SOC calculation module estimates the current driving range of the vehicle, and the estimated value of the driving range is displayed on the display.

Description

technical field [0001] The invention relates to a device and method for estimating the mileage of a pure electric vehicle based on remote data transmission, and belongs to the technical field of remote data transmission. Background technique [0002] With the continuous development of vehicle technology and key parts technology, various electronic systems and equipment on vehicles are becoming more and more complete and more and more humanized. [0003] The penetration rate of domestic automobiles is increasing year by year, and people's understanding of automobiles is getting deeper and deeper. Therefore, when buying a car, people not only pay attention to the mechanical properties of the car itself, but also pay attention to various electronic systems and equipment related to the car. [0004] Since the 1980s, foreign automobile manufacturers have equipped their vehicles with multifunctional control / diagnostic systems, which can warn drivers when the vehicle fails. With t...
