In this paper, we propose a torque vectoring controller for an electric vehicle with two electric machines which drive the front wheels independently. The torque vectoring system includes a vehicle dynamics controller and a motor torque and wheel slip limiter. The vehicle dynamics controller is designed as a polytopic, linear parameter-varying (LPV) gain-scheduled controller. The LPV controller...

Various forms of electronic stability, traction and launch control have existed for over two decades, improving safety, sports performance and off-road capabilities of vehicles. These technologies involve individual control of each wheel’s drive torque or braking force in response to the dynamics of the driving conditions and the driver’s intentions. With the exception of launch control, applic...

This paper presents an analysis of the stability of an electric vehicle equipped with in-wheel motors of permanent-magnet type during a class of electrical faults. Due to the constant excitation from the permanent magnets, the output torque from a faulted wheel cannot easily be removed if an inverter shuts down, which directly affects the vehicle stability. In this paper, the impact of an elect...

The article presents the methodologies based on multi-body systems used to analyze the dynamics of rail vehicle in motion in a straight line. Study of the railway vehicles dynamics requires the creation of three mutually independent models: the model of the vehicle, the track model and a model of the wheel – rail contact. A railway vehicle model developed in the multi-body systems convention w ...

Based on the line-controlled chassis platform, low-speed outer rotor motor is used to drive wheel directly in designed in-wheel electric vehicle. The power system parameters of four-wheel independent vehicle are matched and simulated by offline simulation. Firstly, based theoretical basis research parameter matching pure vehicles, type selection hub battery carried out according established dyn...

Road departures account for nearly one-third of all fatal crashes. Lane departure warning (LDW) and lane departure prevention (LDP) have the potential to mitigate the number of crashes and fatalities that result from road departure crashes. The objective of this study was to predict the effectiveness of LDW and LDP in preventing road departure crashes if all vehicles in departure crashes in the...

Direct Yaw moment Control systems (DYC) can maintain the vehicle in the driver’s desired path by distributing the asymmetric longitudinal forces and the generation of the Control Yaw Moment (CYM). In order to achieve the superior control performance, intelligent usage of lateral forces is also required. The lateral wheel forces have an indirect effect on the CYM and based upon their directions,...

The motor car is a ubiquitous feature of modern life, and most of us spend significant amounts of time in a car, behind the wheel. Driving a vehicle requires complex coordination of cognitive, motor, and sensory skills. All of these aspects can be affected adversely by diabetes per se, with hypoglycemia being the main concern for people with diabetes who drive. Here we introduce the concept of ...

The objective of this research is the replacement of hand weeding in organic farming by a device working autonomously at field level. The autonomous weeding robot was designed using a structured design approach, giving a good overview of the total design. A vehicle was developed with a diesel engine, hydraulic transmission, four-wheel drive and four-wheel steering. The available power and the s...
