“…Due to the pressure of environmental pollution and energy crisis, electric vehicles (EVs) have attracted much attention. [1][2][3][4] The wheel hub motor drive vehicle can shorten transmission chain, increase efficiency and make structure more compact because of the elimination of transmission system, transmission shaft and differential. 5 Compared with traditional fuel vehicles, wheel electric vehicles have higher control accuracy and faster response speed.…”

To improve the ride comfort of wheel drive electric vehicle, a quarter dynamic model is established for vehicle active and passive suspension. Based on the response root mean square (RMS), the evaluation index of vehicle ride comfort is derived. According to the influence of uncertain parameters on system minimum RMS, the optimal vehicle parameters are determined. To avoid experience value of uncertain weight coefficient affecting the LQG control, analytic hierarchy process (AHP) is adopted to determine the weighting coefficient of vehicle performance evaluation index. And the LQG controller of vehicle active suspension is designed based on optimal control theory. Compared with the analysis results of passive suspension, the effectiveness of active control scheme is verified.

“…18 In addition, a single-pedal control strategy for regenerative braking was proposed to evaluate the energy utilization rate of the pedal. 19 It can be seen that a great deal of research has been conducted on automotive pedals. In terms of the evaluation of a brake pedal, one method, based on biomechanical evaluation, depends on testers' subjective feelings, and the results may be limited to the understanding of experts.…”

Due to the considerable increase in car parc and the remarkable improvement in vehicle properties and cost performance, higher requirements are being placed on driving comfort. With regard to the braking system, the enhancement of the brake pedal feel is one of the ways to improve the comfort, and affecting factors include spatial layout, dynamic characteristics, and the characteristics matching with the vehicle motion, so a comprehensive evaluation of a brake pedal is highly essential. This paper, by taking passenger cars in China as the research object, established a comprehensive evaluation system for pedals based on the improved analytic hierarchy process. The index weight in each index level was determined through the G1 method, and an experimental design was conducted on individual indices on the lowest level. The relationship parameters between the indices were measured through the test and comprehensive scores of each automobile pedal were obtained in combination with the evaluation method designed. Based on comprehensive scores, a typical analysis on 16 test vehicles was carried out, followed by a comparison of different index levels. Through result analysis, the direction for pedal improvement was proposed, and the feasibility of the method with the case is verified, which provides a scientific basis and a reference for vehicle pedal development, the calibration in position layout, and the pedal design.

“…It is expensive and large for the development of FCIRTS, and not suitable for the commercial application of low-cost FCIRTS. In addition, the output voltage of fuel cells is low and the dynamic response performance is poor, and the fuel cells cannot meet the power demand of the vehicle in time because the working state of the vehicle always changes in a large range [21,22]. So the DC/DC converter used in the fuel cell vehicles can play the role of voltage boost and power regulation.…”

A control approach for alternating current disturbance signal of fuel cells based on MOSFET high‐speed switch

et al. 2021

Internal resistance is currently one of the most effective ways to achieve the performance improvement, control optimization, and on-line fault diagnosis of fuel cells. In the fuel cell internal resistance test (FCIRT) system (FCIRTS), the alternating current (AC) disturbance signal is mainly achieved through the use of DC/DC converters or other expensive program-controlled equipments, which are expensive and large, and it is not conducive to the commercial application of low-cost FCIRTS. In particular, for the fuel cell vehicles based on dual-source motors, the DC/DC structure is cancelled. Therefore, a new method should be used in the FCIRTS. To solve this problem, a low-cost fuel cell AC disturbance signal control approach based on MOSFET high-speed switch was proposed in this paper. In the approach, a circuit model of MOSFET high-speed regulation was built, and the AC control of the fuel cells was achieved finally by simulation analysis and experimental verification. The proposed approach can not only independently control the AC components, but also save the system space and cost because of reducing reliance on DC/DC converters and dedicated equipments. Therefore, it is of great value to the development of low-cost, high-precision, and real-time FCIRTS.
