Abstract: The paper presents actual benefits and drawbacks of a multidirectional autonomous hovercraft conceived with limited resources and designed for indoor exploration. Recent developments in the field have led to the apparition of very powerful automotive systems capable of very high calculation and exploration in complex unknown environments. They usually propose very complex algorithms, high precision/cost sensors and sometimes have heavy calculation consumption with complex data fusion. These systems are usually powerful but have a certain price, and the benefits may not be worth the cost, especially considering their hardware limitations and their power consumption. The present approach is to build a compromise between cost, power consumption and results preciseness.
Abstract: FlexRay, as a communication protocol for automotive
control systems, is developed to fulfill the increasing demand on the
electronic control units for implementing systems with higher safety
and more comfort. In this work, we study the impact of
radiation-induced soft errors on FlexRay-based steer-by-wire system.
We injected the soft errors into general purpose register set of FlexRay
nodes to identify the most critical registers, the failure modes of the
steer-by-wire system, and measure the probability distribution of
failure modes when an error occurs in the register file.
Abstract: In automotive systems almost all steps concerning the
calibration of several control systems, e.g., low idle governor or
boost pressure governor, are made with the vehicle because the timeto-
production and cost requirements on the projects do not allow for
the vehicle analysis necessary to build reliable models. Here is
presented a procedure using parametric and NN (neural network)
models that enables the generation of vehicle system models based
on normal ECU engine control unit) vehicle measurements. These
models are locally valid and permit pre and follow-up calibrations so
that, only the final calibrations have to be done with the vehicle.
