摘要

Electrification of the powertrain, digitalization and modularization of the vehicle, and automated driving functions are leading to a major change in system vehicle development and in future vehicle production. Electrification facilitates the production of vehicles by using larger functional modules. This simplifies the development and production, especially of so-called purpose-built vehicles. These vehicles are designed specifically for certain use cases and optimized in terms of functionality and cost. Since the number of units is usually relatively low, it is worthwhile using platform concepts. This is particularly appropriate when the available development resources are limited. Preconfigured corner modules are therefore an interesting solution for this vehicle segment. The functional and technical requirements on the vehicle, its propulsion and the chassis components have been derived based on a market analysis of goods transport and the resulting needs in terms of payload, utilizable volume, speed and range. This presentation discusses the concept of a corner module for an urban delivery vehicle. The corner module adopts the “ready-to-use” approach because the inverter and chassis electronics module is highly integrated, including the related software. A special innovation value results from the combined drive/brake unit, which is operated by an electro-mechanical brake as well as an in-wheel-motor, enabling optimum wheel-individual recuperation and controllability. Due to the reduced load cycles, a downsizing of the wheel brakes might be possible.
