To improve safety on commercial cars, a multivariable Global Chassis Controller (GCC) design, involving braking and steering systems is proposed. In case of emergency (e.g. loss of manoeuvrability), the GCC uses the braking system to handle the problem. But, in case of inefficiency of the braking system (e.g. due to low road adherence, large yaw rate error or actuator failure), detected by a br...

As far as the design of SPDs is concerned, the need exists for simplifying its circuit structure in fulfilment of the prerequisite condition of protective reliability. The circuit simplification for SPDs is of benefit to lower the cost of manufacture and reduce the size of chassis. Considering that the traditional SPD that has been extensively used on single-phase AC power supply lines requires...

During the Summer of 1997 Nomad a planetaryrelevant mobile robot, was driven via satellite link for more than 125 miles in the Atacama Desert of Chile by novice operators in North America, demonstrating many technologies relevant to robotic exploration of the planets. An innovative \transforming" chassis was demonstrated which uses a simple linkage to change the footprint of the vehicle from a ...

TRIUMF’s Central Control System has a large investment in CAMAC. To protect this investment but allow the current trend of PCI-bus based computers to be supported, TRIUMF has configured a PCI to CAMAC system. In this setup, TRIUMF has connected PCI based computers into the CAMAC equipment of their Central Control System. DEC Alpha computers running OpenVMS have been interfaced via the PCI bus t...

What does the invention do? This invention presents a modular system of units that can drive, brake, steer and suspend an electric vehicle. These units are also referred to as “Robot Wheels” because they are autonomous elements that can be connected to any electric vehicle chassis. Each unit (Fig.1) includes an electric motor, a steering element, a suspension arm and a connector. The system fit...

Over the last decade there has been an increasing interest on power drive train topologies for hybrid electric fuel cell vehicles. A review of previous publications revealed that little work provided direct comparisons between the topologies. This paper details the development of a simulation model that has formed the basis of an assessment of all the topologies, addressing the advantages and d...

In this research, vibration control of national engine (EF7) using active mounts is studied for two different mounting layouts. The first layout is based on the current engine mounting of national engine (system of three passive mounts), but the hydraulic mount is substituted by an active mount. The other mounting layout contains 4 mounts, 2 of which are active ones and the others are passive m...

−Automotive transmission efficiency measurements are usually performed on purpose-built rigs. A simple model was developed for calculating the overall transmission efficiency of passenger cars by using a chassis dynamometer. Wheel power and engine output were measured, and these values were used for calculations. The proposed method can only be employed for vehicles with manual drive because it...
