Proven pedals for future truck generations

Leading European manufacturer KYOCERA AVX Components has launched the latest series of accelerator pedals for trucks – and they’re all set for whatever demands the future may hold.

Electronic accelerator pedals for passenger cars from several well-known car manufacturers were already well established in the market when the first development of an electronic truck pedal went into series production in 2004. Since then, KYOCERA AVX Components has steadily and successfully expanded its portfolio in the truck sector, and today, it is one of the world’s leading manufacturers of truck pedals.

Proven mechanics with state-of-the-art electronics – many of the leading truck manufacturers rely on this, with their vehicles having to withstand the highest loads. In Asia too, especially in India and China, the pedals have conquered a market and in many cases prevailed over the local competition. Optimum fuel efficiency via the driveline is important, as is the ‘feel’ for the driver. After all, the accelerator pedal is the interface between the driver and the machine, often over many thousands of hours and more than a million kilometers.

Accelerator pedals from KYOCERA AVX Components have proven themselves millions of times in the field, and are already used in e-trucks. They combine the advantages of state-of-the-art technology with proven components at low weight, and are proven to be very robust and durable. The latest generation of pedals is able to provide feedback to the driver about their driving behavior, or communicate information from supporting systems via a haptic signal. A suspended pedal variant also offers add-on options for retrofitting the haptic module at a later date. Read more about this pioneering technology here.

DC voltage is converted into pulses with low loss

In all DC-DC applications it is necessary to split the DC voltage into pulses. This high-frequency on and off switching results in high power losses. Using new semiconductor technology and optimized current management, a significant increase in switching frequencies can be achieved, while simultaneously reducing losses.

Novel technology enables power density of more than 3kW/litre

This technology was developed with a focus on on-board chargers (chargers installed in the vehicle). The core element is a very low inductance design that makes it possible to greatly increase the switching frequencies. By using a new semiconductor technology (gallium nitride), this high switching frequency can be implemented with very low power losses.

Small footprint means higher performance and shorter charging times

The consistent approach to reducing power losses leads to a very compact design, high efficiency and, most importantly, leads to economic advantages. In addition, the higher power density makes it possible to markedly increase, and in some cases even double, the power output for a given installation space. This becomes tangible when, for example, considering halving the charging time for a passenger car.

Georg Schafrath (Managing Director) and Gerd Köck (R&D Manager) at KYOCERA AVX Components (Salzburg) are delighted with their recognition in the WIKARUS Innovation Competition, and are confident in their highly effective invention. Faster charging times are a particularly important focus for the Salzburg experts, as their innovative solutions make an important contribution to the future adoption of electric drives.

The overall strong economic case makes the innovation attractive for versatile application in the automotive industry, but it is also suited for use in solar inverters. For a technical discussion, please contact us here.

Position sensors support
ASIL D capable assistance systems

Position sensors by KYOCERA AVX support ASIL D capable assistance systems for braking force control and recuperation
KYOCERA AVX stands for the development and worldwide production of position sensors based on versatile technologies, and with different electronic interfaces. Our position sensors have already proven themselves millions of times in automotive applications, and take on important functions in new types of assistance systems.

Position sensors for the assistance of braking processes
By sensing the pedal position, the driver’s braking demand is detected and interpreted by the downstream systems. Common applications are brake boosting and emergency braking assistance, i.e. safety-related systems. In the future, they will be used across all vehicle classes to increase safety on the road. Position sensors from KYOCERA AVX require little installation space and can be integrated economically using modular concepts.

Position sensors initiate recuperation
In electric vehicles it is also about the recuperation of the braking force, which replenishes the battery charge and thus increases the available range. Depending on the vehicle model, the rate of recuperation is specified by the electronics, and the process is initiated by detecting the accelerator pedal or brake pedal positions. With the appropriate system settings, it is even possible to drive a vehicle in normal road traffic using only the accelerator pedal, the brake being needed only for emergency braking.

Safety-relevant functions for position sensors
The requirements for these systems are very high, and again the detection of position is the trigger for safety-relevant processes in the vehicle. KYOCERA AVX supports the application with position sensors that meet corresponding FUSI requirements on the ASIL C level.

Broad technology base and many years of field experience
Different sensor technologies allow individual tailoring of the product characteristics to the respective application. Interfaces including analog, PWM, PSI5, SENT, CAN, LIN and other protocols are possible.

The individual design of position sensors is based on the selection of the optimal technology for the application, in combination with a suitable mechanical interface. Based on an advanced overmolding technology developed by KYOCERA AVX, we use the excellent properties of thermoplastic and thermoset to create solutions with integrated sensor technology. However, we are also happy to offer molded or laser-welded cover solutions if this is the optimal solution for your application.

We are at your disposal for inquiries and technical discussions: feel free to contact us, or find out more by watching a short video on position sensors, available as part of our virtual exhibition stand.
