Toyota Hybrid System is the innovative powertrain used in the current best-selling hybrid vehicle on the market—the Prius. It uses a split-type hybrid configuration which contains both a parallel and a serial power path to achieve the benefits of both. The main purpose of this paper is to develop a dynamic model to investigate the unique design of THS, which will be used to analyze the control ...

In this paper, integrators’ and suppliers’ relative focus on component versus architectural knowledge during a potential paradigmatic shift in technology is studied, using the electrification of the vehicle’s powertrain as a case. US patents granted to six automakers and two of their battery suppliers during the period 1976 – 2009 form the main empirical basis. The study provides empirical supp...

Given that power-split transmission (PST) is considered to be a major powertrain technology for hybrid heavy-duty vehicles (HDVs), the development and application of PST in the HDVs make mode shift control an essential aspect of powertrain system design. This paper presents a shift schedule design and torque control strategy for a hybrid HDV with PST during mode shift, intended to reduce the ou...

A hybrid-electric vehicle powertrain architecture consists of single or multiple driving modes, i.e., connection arrangements among engine, motors and vehicle output shaft that determine distribution of power. While most architecture development work to date has focused primarily on passenger cars, interest has been growing in exploring architectures for special-purpose vehicles such as vans or...

The method for preliminary powertrain design is presented in the paper. Performance of EV realized by motor torque–speed curve and gear ratio optimization. typical two-zone mechanical characteristic a PMSM traction included optimization program. longitudinal vehicle model considered Some examples try to show calculation possibilities application existing vehicles: Tesla Model S Mini Cooper SE.

Diagnosis of faults in complex, real-time control systems is a complicated task that has resisted solution by traditional methods. We have shown that neural networks can be successfully employed to diagnose faults in digitally controlled powertrain systems. This paper discusses the means we use to develop the appropriate databases for training and testing in order to select the optimum network ...

Modular product design has received great attention for about 10 years but few works have proposed tools to either jointly design the functional and physical architectures or propagate the impact of evolutions from one domain to another. In this paper we present a new method supporting the product architecture design. In new product development situations or in reengineering projects, system ar...
