In order to eliminate the interference and coupling among automobile chassis electronic control subsystems, an integrated decoupling control approach based on neural network inverse method was proposed. The integration of active front steering (AFS), direct yaw moment control (DYC) and active suspension (ASS) was studied. According to Inter-actor algorithm, the reversibility of chassis system w...

The semi-trailer chassis was usually treated as rigid body in many existing literature, which would lead to larger deviation from actual situation. A rigid semi-trailer chassis model was built and flexiblized based on the modal test results in this paper. The tractor semi-trailer with flexible chassis was utilized to simulate the rollover scenarios on high speed obstacle avoidance under emergen...

The Truck Factor designates the minimal number of developers that have to be hit by a truck (or quit) before a project is incapacitated. It can be seen as a measurement of the concentration of information in individual team members. We calculate the Truck Factor for 133 popular GitHub applications, in six languages. Results show that most systems have a small truck factor (46% have Truck Factor...

OBJECTIVE This study presents data from a large-scale anthropometric study of U.S. truck drivers and the multivariate anthropometric models developed for the design of next-generation truck cabs. BACKGROUND Up-to-date anthropometric information of the U.S. truck driver population is needed for the design of safe and ergonomically efficient truck cabs. METHOD We collected 35 anthropometric d...

The miniaturization of mobile phone antennas by means of purposeful tuning of chassis mode resonances is discussed. A simple approach to antenna independent analysis of chassis mode resonances is introduced. A novel technique for simultaneous tuning of a bar-type phone chassis in two frequency bands is presented. The optimum design and placement of capacitive coupling elements for excitation of...

To examine the relationship of ramp design to truck accident rates, this paper presents an analysis of truck accidents in Washington State, plus a comparison to limited data from Colorado and California. We group freeway truck accidents by ramp type, accident type, and by four conflict areas of each merge or diverge ramp. We then compare these groups on the basis of truck accidents per location...

The next generation of compute servers will be based on clusters of compute blades integrated within a common chassis The integration of advanced networking functions within the chassis promises to simplify the deployment of servers on a large scale by eliminating the need to deploy external inter-network devices on a oneto-one basis (e.g., one or more network ports per server). This paper exam...

Substantial advances in European road vehicle emissions have been achieved over the past three decades driven by strengthening revisions legislation and enabled fuel, engine control technologies. As both technology Europe continue to evolve, Concawe has conducted a study examine effects that fuels can on emissions, this case from commercial vehicles. A bus certified Euro VI level delivery truck...

This paper presents an online method for the assessment of the dynamic performance of the chassis frame in a heavy-duty dump truck based on a novel stochastic subspace identification (SSI) method. It introduces the use of an average correlation signal as the input data to conventional SSI methods in order to reduce the noisy and nonstationary contents in the vibration signals from the frame, al...
